I don't think it should be Debian's responsibility to track Trolltech's
API compatibility, especially since many of the current headers support
obsolete features anyway.

Trolltech generally does not maintain complete API compatibility between
major releases, so it's up to upstream authors to target a specific
release of Qt.  If upstream falls inactive, then that software should
just continue to be built with the version of Qt with which it was
targeted, until the old Qt and hence the old software was removed from
the archive.

Debian wouldn't gain much from the effort of splitting the Qt headers,
at the expense of complicating the Qt packages even further.

FYI, this is being discussed on debian-policy as we speak.

My secret to happiness... is that I have a heart of a 12-year-old boy.
It's over here in a jar.  Would you like to see it?
