That's an unequivocal rule.

As such, I'll defer to Jens, Christoph and others on whether your
minimalist blk_interposer hook is acceptable in the near-term.

I don't think so, we don't do short term bandaids just to plan on
ripping that out when the real functionality is there. IMHO, the dm
approach is the way to go - it provides exactly the functionality that
is needed in an appropriate way, instead of hacking some "interposer"
into the core block layer.
