I think this is a great idea.
A well moderated TA only subforum would increase the signal to noise ratio.
The question becomes: Is there a moderator up to the task? If not, it would just end up as another playground for the bearbulltrollfest to continue!
Yes I would welcome this as well. It seems that a good TA thread has become a treasure amongst the trash. There are way to many "BTC WILL CRASH" / "TODA MOON" / "WHEN WILL IT HIT 1000000000000$" posts.
