With all due respect, this is a *huge* sigh for me. I have been trying
to explain endless times why this is *not* true. If it works it's
because we maintainers have been doing quite a lot of hacks to let
things "work".

Seriously, we have discussed this before, and we kind of agreed that
user-facing applications should either be really backwards compatible
or should have the tool suffixed with the qt version. Whatever other
option is just pain for maintainers, be it trough qtchooser or by
letting us renaming tools ourselves.
