Like Aaron, I don't see that there is any other solution to the three
requirements that he listed. Given that, I think it's appropriate that
the API is designed as it is. (Note though that I'm not a fan of the
SQL API in general as I think SQL is the wrong tool here, hope to have
an alternative proposal eventually).

Designing APIs for the web is different from designing APIs for many
other platforms. The fact that the resulting API comes out differently
than elsewhere is not I think we can avoid.
