There's also nothing which disallows it.

To be clear: my opinion is that the header cell/data cell association
comes *either* @headers, @scope or the 11.4.3 algorithm; but HTML4
could be read differently.

So go back read the definition of a rowgroup.

Where have you read such a thing?!

<th scope=row>Foo
<th scope=row>Bar
<td>Baz

associates Foo *and* Bar as header cells for Baz.

Depends on the colgroups, but if you keep the default of having a
single colgroup spanning all columns ("A table may either contain a
single implicit column group (no COLGROUP element delimits the
columns)", ยง11.2.4), then yes "C s / s s" would be what happens.
