Thus I proposed the second idea with a code-only solution
to optimize performance (force user-configured minimal

This isn't about whether the metadata compresses, this is about
whether ZFS is smart enough to use all the space in a 4k block for
metadata, rather than assuming it can fit at best 512 bytes,

I sent a zvol from host a, to host b, twice. Host b has two pools,
one ashift=9, one ashift=12. I sent the zvol to each of the pools on
b. The original source pool is ashift=9, and an old revision (2009_06
because it's still running xen).
I sent it twice, because something strange happened on
