There aren't many, but at least one that I care about exists.  The
case is one-off throw away addresses.  When I send a message, I
generate an address crypto-based on the recipient and the time-frame I
expect a response.  I don't want mail coming back outside the
specified response period.  A bloom filter can't do this†.  A state
machine driven trie can.

The acceptance criteria are not relevant.  If they can be expressed as
part of the restriction list, they are valid.  And there are several
that I'm not going to get into arguments with people about over their
validity.
