Shouldn't zonefs (in addition to the pending btrfs and nvmet patches)
start using this new value instead pf the physical block size?

Yes for zonefs. I will add one patch to this series for that.
For nvmet patches, I will let Chaitanya handle that.
For on-going btrfs, I think we can cover that with btrfs-progs (check in mkfs)
for now and add a patch as a fix in 5.12 to check the FS block size on zoned
devices, if the series is accepted. Patching now would cause the btrfs tree to
not build.
