AS does look for artwork in the extrafanart folder (and has since before I started maintaining it). That seemed to be the unofficial standard for a long time before Kodi 18 shipped so I left it to maintain compatibility with other addons that download artwork.

Updating AS for the new artwork structure has ended up not being trivial (mostly because I'm going to have to have a routine to move and rename every piece of existing artwork AS has downloaded), and I've been waiting to make sure the new artwork structure stabilized, so it's going to be awhile.  Honestly every time I read up on the new structure it seems overly complicated and requires lots of manual work to get it activated, so my motivation to do the major rewrite wanes.  But I'll see if I can't get myself excited about it and do the updates.  I'll also include updates so those folders aren't created if all the download options are turned off.  That isn't a use case I thought about before.

Ok, thanks for the explanation and understand the extra work involved.
