Right, but mechanically, one has to ask the instance
before getting the schema. It seems inefficient.
And with a DOCTYPE, one could parse subtrees by
changing that value and ignoring the outer
tags. Not always but occasionally useful so
yet another lost functionality.

Not really. In SGML the DOCTYPE declaration had to say what the root
was, because the start-tag of the root element might not appear in the
instance due to start-tag omission. In XML there is no start-tag
omission, so it is redundant to specify the root in the DOCTYPE declaration,
as it always must agree with the first and last tags in the instance.
