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.
