I can't quote you chapter and verse - as I say, I cannot
reproduce it here - but it happened at a number of user sites
and caused a lot of grief.  Also, you need to take the utmost
care with the installer.  If any 'stale' files remain from an
older install (perhaps you dropped a resource or two in a later
version) then your code signature is invalidated.  And if a user
should drop a file into your resources folder...

No, it's just too fragile, sorry.

If that really happens it would break a lot of apps for a lot of
people - it'd be interesting to find out what your users are
seeing. But probably no longer related to use of Xcode...there's
an apple-cdsa list for discussing the security architecture (and
the guy behind code signing hangs out there, he'd definitely
want your bugreport number for that issue).

Cheers,
Graham.
