I'm not sure I understand the objection here. The form suggested by
Drew just gets a list of font names -- it doesn't load anything, so it
should be harmless?
And the doc string of describe-font seems to be wrong. You can ask it
to describe a font that's not loaded. Or at least it seems that way
when I test it.
