(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I don't think this would be an appropriate feature for Emacs core -- it
would be too surprising if Emacs was setting `indent-tabs-mode' based on
external factors like this (and I'm sure there's a lot of other hints it
could be taking from other VCs).

It does sound like it could be a useful ELPA package, though, but I'm
closing this wishlist item in the Emacs bug tracker.
