I don't see why you call this "risky". "svn info ." doesn't give as
much version information as "svnversion ." does, but it's still
useful.

I don't see why someone would ask for that. I would only want svn
update to change a file if I asked for that file to be updated. If
the file had a $globalversion$ keyword in it, then I'd have no reason
to complain if it was wrong when I hadn't chosen to update it. I'd
want the keyword substitution to apply to that file when that file was
updated, not at other weird times.

What I *would* want, and this is probably new but I don't know how
major, is for some files to be automatically marked as modified in the
repository whenever any file is checked in. If this were done with
regular keywords, it would be a reasonably heavy burden: those files
would have to be tracked down and found. But presumably this keyword
could be handled specially, so the repository knows the list of files
that contain it and automatically marks them as modified.
