The desktop-specific mimeapps.list is scanned first, and then the generic one.
The generic one cannot override the desktop specific one.

So if you have a mimeapps.list which is the same as the old version (eg. basically
the same content as gnome-mimeapps.list), it will not override whatever settings
you have in kde-mimeapps.list, just fill in the blanks.

You can't have Added/Removed associations in the default mimeapps.list, only
in the desktop specific one. Which is of dubious value, unless you want to
say "this desktop file doesn't support this mime-type".

In most cases, you'll want to add that information to the .desktop file in
question instead.
