...having that line running down the trunk, some or all of it being out of your view and under tension during a tree removal is a dangerous and unecessary liability

There is a danger present here already in the technique of butt-hitching logs that fit all of the criteria you are concerned about yet are accomplished successfully and safely on a regular basis.

Dave, I used the word unnecessary because that ground anchor just doesn't need to be there to work the tree using SRT. Re: butt-hitching, in most cases having the ground anchor is necessary to carry out the operation.
And I wasn't only referring to the risk of the climb getting hit by a log either i.e. I was working with a crew once in New Zealand, devoted Christians they were....I had to be extra careful so not to use bad language or anything like that as it didn't go down well at all.
Anyway, I came down from the tree one day to find that the tail of my climb line had been badly cut, must have happened while they were all cutting and shifting brush from around the base the tree....yet nobody seemed to know anything about it when I asked!
I wasn't happy but it wasn't the end of the world either as I didn't feel like I'd had a close call or anything i.e.
When descending using DRT a climbers tail end is always visible before the friction hitch runs over it (in theory) which obviously works in his favour should it unknowingly get damaged....but with SRT, well its not just the visible tail end you need to worry about!
Hey, its cool and I wouldn't want to discredit the technique or anyone who uses it, but as well as not being able to maintain a constant view of the line with everything that goes on, there's just know way I'd trust anyone sawing and working around that ground anchor with my life depending on it....why on earth would I want to do that when there’s an option of anchoring it way up high in the tree?
Incidentally, we've had a couple of mishaps over the last week.... first I nearly got hit by a swinging log and then on Thursday my spike came out of a dead cedar and I got slammed face first into the trunk
....just bracing myself for no.3 now! Although you can be sure it won’t be SRT related!

Reggie, this is exactly the reason why I chose to quote you and what I appreciate about your responses in regards to rigging and climbing. You are knowledgeable and polite.
On the first quote above, I was not questioning the ability of the SRT line to be able to be anchored above. Merely that on a daily basis you are working with a highly tensioned line that is often times not visible to you, handled by untrustworthy groundmen where the outcomes of each cut can affect many lives, not just your own. Yet you accomplish this successfully over and over because you have learned the limitations and dangers of this setup.
Your description of the groundman cutting the tail of your doubled rope is all too common of a scenario and a very good reason to take the extra time and pull up that tail prior to chainsaws and feeding of the chipper if it is in the same vicinity. Toss it out of the way if you can; if you can't, hang it from the tree.
You referenced again not trusting the groundcrew to stay away from a tied in support line. Yet this line can be set up at your discretion to not be accidentally accessible to the working area. These same ground crew, who are so incompetent that they can't be trusted anywhere near the vicinity of that line, are the ones that the industry is demanding carry the equipment to rescue a climber. There are plenty of circumstances that could disable you that don't involve injuries and will not be 100% avoidable. (Such as medical distress issues.)
So would you rather have your groundmen lowering you in a fashion with which they are already somewhat familiar or strap on some very unfamiliar climbing gear and tie you off with their version of a safe knot to get you down?
Even with my strong advocacy of this technique, I fully understand that it is not achieveable in every situation.
Dave
