Hi Reinette,

You are quite right; I am in complete agreement with your assessment. The
primary intention behind limiting the scope to io_alloc was indeed to avoid
the complexities associated with L2 asymmetric domains.

Are we all in alignment to focus this feature entirely on io_alloc for the
time being? If so, I will be pleased to prepare a follow-up series that
reflects this consensus once our wider discussion has concluded.
