Yes.

Disagree.
The API would embody the abstract syntax tree directly (for an overly
generic comparison, consider the DOM). Passing such abstract queries to
an XQJ driver might involve serializing them, but the API need not
determine the form ... serialization as XQuery strings would be a
straightforward option.

Disagree (for the most part).
Whilst there are cases where API design can interact awkwardly with
underlying representations (more generally, interfaces can interact
awkwardly with implementations) I don't see how that could apply in
this case.
