I still don't understand what the applicability is, but if that statement about MIL-STD-461 applies to products to be sold commercially, it has serious issues and drawbacks that make it utterly impractical.
I suspect the choice of MIL-Standards was made to reduce emissions more than FCC rules require and thus increase the margin available to prevent interference in the marketplace.
The problem with lower numerical limits is, however, that either they become prohibitively expensive to manufacture, or they will be adopted pro forma and ignored in practice – which is often what manufacturers do already facing FCC limits. It does not help to require compliance with standards never meant to apply to consumer devices.
A reasonable default limitation – Part 15 – can put a ceiling on the number of interference complaints, and a predictably expensive penalty for actually causing interference could ensure that manufacturers actually complied with those limits, thus my suggestion to require a manufacturer warranty covering the costs of remediation should interference occur. I think that might be enough; if coupled with a warranty against susceptibility to nearby transmitters, it could substantially reduce the number of complaints from that side as well.
