I know this is a topic proposed for the maintainers summit, but given
the number of people who seem to have an opinion and be interested in
dicussing it, would a session at LPC be a better candidate ? I don't
expect the maintainer summit to invite all relevant experts from all
subsystems, that would likely overflow the room.

The downside of an LPC session is that it could easily turn into a
heated stage fight, and there are probably also quite a few arguments
that can't really be made in the open :-S
A separate LPC session for a subsystem or set of subsystems to explore
local passthrough policy makes sense, but that is not the primary
motivation for also requesting a Maintainer Summit topic slot. The
primary motivation is discussing the provenance and navigation of
cross-subsystem NAKs especially in an environment where the lines
between net, mem, and storage are increasingly blurry at the device
level.
Would there be enough space at the maintainers' summit for all the
relevant people to join the discussion ?
