Short story, because committing it to hardware is a useless complication.
A standalone port should be VLAN-unaware, or i.o.w. it should not drop
based on VLAN port membership, shouldn't add or strip any VLAN header,
and should forward as if the VLAN wasn't there.

So the behavior of a standalone port is absolutely sufficient as a basis
for an 8021q upper interface to see the traffic it needs, and for the
traffic it sends to reach the outside world as it intended.
