The upstream Postfix distribution does not claim to have delivered
messages to a file without delivering them to that file. If your
vendor modified Postfix, or your OS discards writes for security
reasons, or ... that's not a result of upstream Postfix behaviour.
On my machine (latest snapshot, but the local(8) mailbox delivery code
has not changed in ages):
$ postconf mail_version
mail_version = 3.7-20210605
$ postmap -q bogusalias $(postconf -xh alias_maps)
/tmp/bogusalias
