Now we have another reason to care for this: I have contacted Tig, admin of LvL. Some time ago, I guess after the redesign of LvL, he asked fromhell for a list of OA-compatible maps in the LvL forums. Now that we have that part covered with the linked Wiki page, he's going to use that list to mark the OA-compatible maps on the site. Here's his answer:
That is list a great help. Personally, I think it could be a lot
clearer. As a suggestion, something like a "tick" on the left of the map
name if there are no issues.
Anyway, I'll add the tags over the next few days for the maps without
any issues.

There's a lot of entries to cover. Maybe I'll take that work until I return to my home next Monday.
