Literally the last two RSS items right now are about how splitting packages will require intervention for some users (plasma and Linux firmware).
Maybe a nitpick, but the linux-firmware situation is different, it's not about needing to install extra packages (they turned the existing package into a meta package or whatever it's called), but about that coinciding with some changes that can break the upgrade process and require you to force uninstall a package before proceeding.
But yeah, good point about plasma, the only differences I can even think of are that plasma is probably more popular, and definitely more important to have working.
