I tend to agree with your conclusion that that's a whole lot of
infrastructure with very little return. I don't see anything here
we shouldn't do via function hooks instead, and/or a "register" callback
from a dynamically loaded library.
Also, we tend to think (for good reason) that once something is embedded
at the SQL level it's frozen; we are much more willing to redesign C-level
APIs. There is no possible way that it's a good idea for this stuff to
get frozen in its first iteration.
