I'm afraid if we won't do it default, people can never realize if the
feature exists.
Also, I can hardly imagine how it can get on the way of existing users.
As I can see, it mostly compatible with old behavior:

- tag files probably resides in common path along with the project anyway.
    If they are not, the manpage suggests using GTAGSROOT.
    If the are, the feature is transparent.

- users probably need tags from the current file's project, not some
other one.
- the feature is in parity with default Vim settings for ctags search path.

So I think it's just the most probable scenario for the users, and as
such, it should be default.
But, to be honest, I've never used any tags, so I can be wrong here still.

If you insist on 100% compatibility by default, maybe we could just
implement lookup in the two paths simultaneously (the current directory
and directory of the current file).
