But if most users are testing it with non-Intel hardware, then we need
to be doing the same.  Otherwise, quirks of the specific hardware format
could leak in and break things (or keep them working for you).  I don't
really see that as a solid reason

I don't remember the explicit case you're referring to, but I expect
that I mostly was just lamenting the fact that "bios raid" has
continuously been a source of pain and that this is more.  Throwing
random config things which have to be twiddled into the boot path don't
really reduce the pain for the users (what do we set it to for the live
image, eg?) and it just increases the maintenance pain
