Hi Mike,

I broadly agree with your comments, but I want to note that:

We are still in the midst of a multi-meta-cycle transition to migrate toward
the use of stable kernel device naming, but once that's completed there is
no reason to believe kernel device names will change further. Furthermore,
on any image where we have netplan available, the default policy for the
kernel is to use predictable network device names. So I don't think this
should be an argument for forcing MACs going forward for anywhere that
you're using netplan.
