The "font-lock-<foo>" names are due to history.  There's no point using
this scheme for new faces, especially for faces not directly linked to

How 'bout designing a concise "face description" format, so that instead
of choosing "hi-yellow", the user can choose (say) "b:yellow",
"f:blue", or "s:bold".  This would give access to "any color", and in
order not to overwhelm the user, the completion would default to only
completing among a predefined set (corresponding to the current
predefined faces)?
