Correct.  The mailbox provider agreement would have to be amended so as
to state such clause.  Consent is straightforward for unilateral
developments such as the TrashMail add-on.  When "ISP confirmation"
(this water tight opy-in, that is) will be available, a user should be
able to explicitly request to skip it --and presumably use traditional
COI instead.  That also covers possible implementation bugs.

In practice, it is very difficult for users --or anyone acting on their
behalf-- to obtain a list of current subscriptions:  Waiting for
reminders takes time and is not reliable.  Consistent use of water tight
opt-in would overcome that limitation.
