As always, the gating factor is time, but also that I'm waiting to see
how the draft for the URI template spec shakes out, as it is something
we'd want to use in a standards track version of OpenSearch.
In the meantime why don't we start compiling a document about what
we'd like to see change, and what we'd like to see stay the same, with
the next iteration of OpenSearch.
Please feel free to add to and reorganize that document as you see fit.
