I totally understand the desire to have it all make sense to users. I
wonder if the desire to have something working well in the next 30 days
should override the desire.

My thought is that early adopters are used to this sort of
work-around. "Accept this bit of weirdness, and you get all this
awesomeness". In this case "Register hardware with similar specs as
identical specs, and you will get automatic deployment over heterogeneous
hardware."

If we keep the scope narrow enough, those users only have to wait a few
more months to be able to make their hardware registrations more accurate.
