Let me include more of that quote [1]:

"[...] Essential modules are general and useful for a majority of Qt
applications. A module that is used for a special purpose is
considered an add-on module even if it is available on all supported
platforms."

I agree that according to that definition, QtMultimedia (and arguably
QtSQL?) is not essential.

Though it's going to be hard in some cases to determine if something
is clearly useful for a majority of Qt applications.. I mean, what
about QtNetwork? One could say that is "special purpose", but somehow
I don't think it's going to be dropped from Essentials :)
