WRT the url-matter:

There is no need to delegate proceeding upon a separate function dealing with URL, as the basic scheme already accepts a function.
Just put the appropriate one there.

Also thing-at-point--bounds-of-well-formed-url seems doing a kind of double-check, which seems good as analyze-tool when bug-reporting, but nothing to fire up all the time.

Etc.

HTH,

Andreas
