Personally, I don't use text mode that much, and I don't care, for my personal
use.  

But my guess is that there will be many Emacs users who will be confused by
this, expecting TAB to indent (if not to simply insert a TAB char).  Not because
that's what TAB did in the past in Emacs, but because that's more or less the
behavior many newbies are used to, from other text editors.

My crystal ball whispers to me that there will be lots more questions posed by
newbies, to which the answer will be "Deactivate the region or use `C-q TAB'."

I would suggest keeping TAB in text mode simple, not DWIM.
