I think there are trees in Cheddar Gorge that have signs on them warning against abseiling on them?

I suspect most landowners would be happier with a loose tree bearing a sign warning against abseiling off it than a loose tree with abseil tat on it.

Obviously! I assume you are volunteering to monitor use of the tree and chastise instructors accordingly?

True for individual climbers. Not true for instructed groups who cannot be expected to check the anchors just in case their instructor is lazy or incompetent...
While self-reliance is an important skill I don't think it should be taken to extremes - where information is withheld because climbers should find things out for themselves. Guidebooks often warn of loose blocks and trees, or warn that a route contains loose rock; climbers often share information amongst themselves. Arguably putting a sign on the tree is an act of self-reliance by the climbing community as a whole?
Fundamentally it comes down to two questions.
a) Is the tree genuinely loose and potentially dangerous.
b) Is the tree commonly used by climbers and groups in spite of point a).
If so, then it is an accident waiting to happen. This makes it unusual - most loose things are on less-travelled routes, where people should and do take more care to check anchors etc. Most trees are not that heavily used. Only the combination of these factors would make the risk high enough to warrant mitigation; I don't think it is the thin end of the tree-signing wedge...
