Ah, you mean that he was expecting he should also provide a faked tilde
for Times and Palatino and whatever?  Could be true...  This has nothing
to do with T1, however.

The tilde in Computer Modern OT1 is also raised, it's just that
especially for that font in that encoding url.sty uses a faked tilde.

I don't think this is an issue where Unicode (or any other standard) can
help decide.  Instead, it's a question of font design.  And as to your
question, changing the font itself is a very bad idea, because people
rely on it being constant (and perhaps the license would even forbid
this without renaming the font).

So in fact, either you create a new url.sty (under a new name unless
Donald Arsenau agrees) or a new font...  The first is easier, of
course.
