But you literally only added a power source overlay for the one example I
cited. I'd list all the other symbols which should also get power source
overlays, but this is twice already I've listed things I don't want added
to the symbols-new file that you go ahead and add anyways.

I don't think it's better to instead rely on a user's cognitive load to try
and understand the alphabet soup coming out the other end.
It seems like you're driving towards defining a meaning for all 3496
symbols, but you don't seem to think that's a prohibitive number of letter
meanings or subtly different icons for users to learn while they're staring
at a map. What's the expected user experience where this isn't a huge
problem for new users?

Then why are there 60Hz and 50Hz Utility overlays?

Then I'm not interested in promoting the PWR extension. I proposed this as
a way to focus the roll of symbols and get them out of the power source
business, not to add a second class way to represent the same information
when you clearly want to keep symbol overlays as the primary method to
indicate power source. APRS already has plenty of duplicate ways to
represent the same information; I don't want to add power sources to that
