In the case where we augment the existing spec with a new way of
encoding the content in (new) headers, we can specify that repeat
(new) headers encoded that way are illegal.

That doesn't change anything in the base spec, it merely imposes a
tighter restriction for a subclass of (new) headers.

In the case where we implement a new semantic layer, that will
by and large be a replacement of the base spec, so we're free
to do what we want, subject to the necessary interop/compat
considerations.
