Changing a font still works.
Due to the change to clear font styleName property when saving via
KConfig (D27735), if in kdegloblas you removed the ",Regular|Normal|Book|Roman"
from the end of the *font*= entries, openin the font selection dialog
in the KCM, the very first style is selected, not "Regular" and co. as
it should be. This will be addressed in an upcoming diff.
