True, but SMTP and related standards/practices have long suffered from
lack of attention to standardizing things like:
- list functions & behaviors (or we wouldn't be dealing with the impact
of DMARC on lists)
- the administrative realities of running mail systems and lists - such
as trying to track down things like who's sending bogus unsubscribe
requests, or who's been using their "spam" button as a delete key
(things that get very hard when, for example, someone is forwarding list
mail to a new address, but has left their old address on the list - I
can't tell you how many times I've been asked to remove someone from a
list, and simply can't find an address that remotely resembles the one
they send the removal request from)
Various hacks like "Apparently-To:" are practical measures to address
situations that are simply not addressed in a standard way.
They cause their own problems, of course - but....

In theory, there is no difference between theory and practice.
In practice, there is. .... Yogi Berra
