I believe that's almost certainly correct: it was done for performance
reasons.

This goes right back to my long-standing feeling that album artist(s)
roles need to be assigned  for _every_ album at scan time. Without them,
the queries and the logic involved just to generate an album's "by" line
are very inefficient. A page requiring the display of dozens of albums
can require hundreds of queries instead of the single query that should
be necessary.

I'm not aware of any place where it is -not- shown for albums. Have you
found one?

That makes sense and would be reflected in the rewording of this option
to 'Treat TPE2 MP3 tag as Band/Album Artist' that came much later.

It _is_ being used? That's not my understanding. Is it only used with
Mp3/ID3v2 tagging?

I'd have to defer to Phil as to what this option should or could be used
for. In the other recent thread on the subject, he mentioned a situation
where he thought it was necessary, but I never fully understood the
reasoning.
