I was about to clarify the question regarding the devices above (my
question was more specific to how devices events are synthesized when
interface renaming is involved), but this tidbit actually clarifies the
issue.

Thing is, I've actually been using UseDefaultInterface=true in iwd.conf
as well. So, in this case, does the race actually exist?

So talking in general terms, and without requiring the admin to list
specific interfaces, if iwd is done After=systemd-udev-settle.service
with UseDefaultInterface=true, no double-renaming should happen for the
interfaces directly detected during boot?
