to overide me as the author and maintainer of this code.

Since when was acting behind the scenes a good argument for anything?

It doesn't.

The whole point we have native multipath in nvme is because dm-multipath
is the wrong architecture (and has been, long predating you, nothing
personal). And I don't want to be stuck additional decades with this
in nvme. We allowed a global opt-in to ease the three people in the
world with existing setups to keep using that, but I also said I
won't go any step further. And I stand to that.
