Comment (by asn):

 Hello team,

 how should we proceed here? I hear two explicit "yes" from me and dgoulet,
 a few valid concerns and discussion, and zero "no" so far. In this case,
 should we proceed with merging this?

 I can also make tickets for various future improvements here like:
 - Investigate bloom filters for replay cache to increase them to much
 bigger sizes.
 - Investigate reinstalling a timestamp of some sorts to the INTRO cell to
 avoid replays?
