That is exactly why we enforce min 4k everywhere here too, but its not
for everyone which is why I stuck to 512b default when I added it.

I guess the big question is:

Is future compatibility vs performance the right way to go for the default
as those what want the absolute best performance could always reduce the
value prior to creating / added top level vdevs?
