I think it's too much effort to keep a list of attachment directories
which have been created by Org attachment commands.  Complexity!  (BTW
org-attach-sync does not create an attachment directory.  It rather
checks the state of the directory and acts accordingly.)

Please recall that only empty attachment directories would be removed,
so removal of a directory--and in particular one that existed before its
interpretation as Org attachment--wouldn't be a big deal AFAICS.

To be honest I'd rather not make another customizable thing out of it to
keep the overall complexity low.

OTOH we could easily introduce e.g. customizable
org-attach-delete-empty-dirs-on-sync.
