Except with this list there are three different versions, so people
receiving the digest wouldn't be able to use it.

Nasty, most lists I've seen usually have a timeout period of two or
three days to avoid just that.  A two hour (or less) window is
ridiculous since SMTP can have delays far longer than that.

Some mailing list software allows for this (e.g. Mailman and Sympa),
but the software used for this list doesn't.

This list does have that from the moment the confirmation is received,
as do most lists.

This would be a *very* bad idea.  It is way too simple to spoof an
email address and with a configuration like that every single person
known to be subscribed (i.e. every person who posts) could be
unsubscribed by someone else.  As the behaviour of confirmation
messages is (usually) global, then the reverse would be true and
people could be arbitrarily subscribed by an unknown party.

The whole purpose of a confirmation message is to prevent nefarious
individuals from making changes to the receipt, or lack thereof, of
another person's correspondence.
