Yes, they're basically the same. But in that context "easier for virtual
users" means "easier if all your users use the same uid", since most
people use the same uid for virtual users.. (I don't think wiki confuses
these two things?)

Yes, because SETACL updates also the shared-mailbox file, which contains
information about what mailboxes are visible to who. Without that,
Dovecot would have to look through all users all mailboxes to see if
there happens to be any dovecot-acl files that contains rules for
current user, which of course would be really slow.
Maybe for v2.0 I could add doveadm acl command to help with these
