Not yet.  That would require a lot of duplicate commits in the bug
fixing and cleanup phase.

Well, the first ideas are:

- A function for deleting a PR should be added.  This is only seldom
  used, but it's sometimes useful and can also be used e.g. by
  maintenance tools.

- Maybe it's not *necessary* to force backends to implement full query
  handling.  We probably can agree on that writing new backends should
  be as simple as possible.  I can imagine that your `query_pr' function
  could be only optional and there could be available simpler versions
  of query functions that can get a list of all problem IDs, a
  particular PR and maybe also optionally some index (similar to the
  current one).
