I am not sure I understand this comment. Memento is not a program. It
is an HTTP-based mechanism to access resource versions. And Memento is
not about preservation but, in some cases (eg web archives), is used
as the protocol to access preserved materials.

I did a tiny presentation on Memento at the Maastricht IETF indeed. It
was very early days of the protocol. It eventually took 4 years and a
lot of testing and interactions with varies parties to finalize the
protocol specification.
