Having a central place sounds like a particularly good idea, IMO.  I
usually don't use contributed module because they are prone to
security issues.  If all the escaping was (forced to be) done in a
central place, it would be ten times easier to audit the code (before
installing it).  Whether this is feasible in the theme layer, I don't
know.  I do know, however, that I like the idea.
