If "common sense" won't cut it, do I need to start a vote, forum thread
or something else asking KDE users (I can do it for Gentoo alone) if
they are worried/upset about this? Should I ask how many "former KDE
users" stopped using it because of the MySQL dep?
If you want, I can point you all to the user rants in Gentoo bugs about
MySQL dependency for KDE as a whole and amarok as one particular KDE app.
Why is it so hard to understand that KDE is getting more and more bloat?
By the way, no other distributions / packagers have issues with the KDE
dependencies?

As Maciej hinted, you're opening the door for another group of KDE devs
later call for precedent to add hard deps on sqlite, postgres or
whatever is their favourite DB. Requiring full blown relational
databases for a DE is probably a good sign that someone is going in the
wrong direction. Again, I can point you to comments by users in Gentoo
bugs complaining about this - it's not just "my individual opinion".
