Indeed, defface already provides the means to account for different
display specs.

Concerning the Modus themes' question, I simply did not know any better
~1 year ago when I started the project.  The tango themes where my point
of reference.  Also, and if my memory serves me well, the command
customize-create-theme did not account for light/dark variants.

Going forward, it may be preferable to follow your suggestion.
