This is a possibility, presuming that we take #2690.  We needed PRIORITY on the request stream so that streams opening before the PRIORITY frame arrives don't erroneously starve other resources until the PRIORITY frame arrives.  #2690 plus reverting initial priority would allow bringing back exclusive dependencies; placeholders were separately discussed with HTTPbis as an enhancement to incorporate into HTTP/3, so I think a decision to revert that would be handled separately.
