They frequently do the rest of the hardware and software separately for consumer and enterprise, so it seems like a reasonable extrapolation.

Yes. Compliance with some MIL-xxx and FIPS-xxx specs come into my mind.

Depending on the company, enterprise and consumer divisions might be totally separate from A to Z. (But I agree with you.)
