But they are not incompatible. Some of them can be exchanged between
different flavored apps, and this is all handled quite nicely by logic in
the code when you open a .kdf file (which has data in it indicating which
app it comes from). Rewriting all of this to use different extensions would
probably add weeks to the development schedule. A lot of behavior could
break that works perfectly fine now.

Different extensions are visible, creator codes aren't. The user doesn't
need to know about creator codes. They don't need to be explained. And I
don't need to write separate documentation for each flavor of the app
everywhere the .kdf extension is mentioned. (there's 4 other extensions as
well that are shared, but I've just been using one for the purpose of
discussion.)

Anyway, as I said, it would be a huge amount of work to change all 7 of
these flavors of the app to use different file extensions (for 5 different
file type - i.e. 7 x 5 = 35 different extensions instead of 5). I accept and
understand that that is a valid recommendation and probably the correct way
to handle it in this day and age, if it wasn't for the fact it would be too
much work to change it now just to correct this minor icon issue. Users with
more than one flavor of the app installed (not a lot) will just have to deal
with it. ;-)

Thanks for the advice.
