Haven't planned on this originally, but it seems like a good idea.
Never really used Obsoletes before, so I have to ask:
what's the dnf behaviour when a package is obsoleted by multiple packages?
If it tries to install all of them, then that'd be okay. I'd like to
avoid a situation where dnf decides that it prefers to upgrade by
removing the "old" fpc package and installing only fpc-ide.
A.FI.
