Why do we need a "standard"?  What's wrong with "prior art"?

most of the folk making such arguments have been at this for said
decade(s)...

That's regretable, but you have to give NetBSD marks for trying.
I have binaries that were compiled over 12 years ago on 386bsd that still
work fine on 2.0 - so I don't buy the "backwards compatability isn't important"
argument at all.
