Feel free to add this feature request to the bug tracker or to even write
the patch to add this function to the layer class.

is it alright to have a method that updates the selection set using the

Imho, the query string has nothing to do with the selection set. If you
first set the query string, you can then select all features left in the
layer.

Best wishes,
