No, but you might need a historian to answer your questions :-)
Although Postfix documentation maintains an accurate record of when
features appeared, for clarity's sake many solutions are written
in terms of the current feature set.
I suggest you look into virtual mailbox domains, using Dovecot as
the delivery agent and POP/IMAP server.
/etc/postfix/main.cf:
virtual_transport = lmtp:host:port or lmtp:unix:/path/name
virtual_mailbox_domains = the domain name
virtual_mailbox_maps = the table with valid recipients in that domain;
Postfix will ignore the lookup result value
