3 are all companies and projects that try to offer binairy versions of their
software and are faced with the question of KDE AND Qt versions.
It is not enough anymore to say you need KDE3 (which implicitly needs Qt3) but
you need to specify you need Qt3.1
I hear many people saying that RPMs are too hard to use (people actually send
koffice bugreports saying our installer gave errors when the rpm wouldn't
install without -force)
It just looks quite bad when installing a package you just bought or
downloaded needs a new Qt, which needs a new KDE. Thats a lot of rpms.. This
is why I mentioned the PR thing.
We only had KDE2 for quite a short time (in company years anyway :) which
makes us look like we did not do binairy compatability very well. We all said
that KDE3 was going to be _the_ platform to develop your apps against.. This
means to packagers that they just need to post 'KDE3 needed' on the website,
and thats it.
This would not be true anymore.
I understand your points, and for a debian user (anyone seen kde3 packages
yet??) it would just be one 'apt-get'. But for most users its 'too hard'.
