I don't think it's so binary. AFAIU (and recall also Linus saying that) it's
ok to make things less optimal for older/less common hardware, if that's the
cost to make the kernel better for the major ones. So that's why we're e.g.
discussing removing CONFIG_HIMEM which could limit how much physical RAM
some 32bit  architectures can use. Or we can have new features e.g. 64-bit only.

We can call that older/less common hardware "legacy" or "museum" or
whatever, I wouldn't say it's diminishing it, just stating a fact.

Of course the devil is in the details so that probably to some extent
depends on what exactly you mean as "requirements" above. AFAIU the
conclusion here was already that ipv6=m isn't consired one for Amiga to
stay, and it's enough to have ipv6=n there.
