What would you consider to be "directly"?  What advantage would you
hope to gain from a different API?

FWIW, it seems unlikely to me that we would consider anything much
lower-level than SPI to be an officially-supported query interface.
You could no doubt run a query by calling assorted backend functions
directly from a PL implementation, but it would be mostly on your
own head whether that worked and kept working across releases.
