That isn't correct. The kepub format does NOT require an XHTML to be marked as a cover. What it states is that the cover image must be in it's own XHTML file, but it doesn't state that this file must exist or how it is found. Experimentation shows that the kepub reader assumes the the first file in the guide is the cover file.

So what I'm looking for is a search in quality check for epubs without a COVER PAGE, where the current search ("cover") presumably checks for epubs without both the cover page and cover image. I assume that if it has a cover page, it also has a cover image.

The existing cover check is only looking at the image.

Epubs without cover pages seem to generate kepubs without cover pages, which do not work properly (unless there is exactly one html/xhtml file).

Sorry, but as I've been stating, that's wrong. The books are working exactly as designed. Your interpretation of this is what I consider to be wrong.
