I don't think we do, really.  Listing the major fonts in a help text
like this would be sufficient.

Not directly, but we could add a mechanism for making Emacs do that.
I.e., as with delayed-warnings, we could add a list of actions to be
performed after redisplay is over...  I.e., generalise delayed-warnings
somewhat.

That's probably overkill.  Say, the first 100 of those in a buffer?
Only the first?
