What are those reasons specifically? Not saying you’re wrong, but just wondering if the less frequent usage of usemap could make the problems easier to tackle than they were with src. That said, even though usemap-N isn’t ideal, the infrequency with which it would be needed makes it not a terrible compromise IMO.

Other attributes to consider: ismap, crossorigin. Crossorigin should be fine; ismap poses similar problems to usemap.
