When I said:

I meant it would cause other solutions to be less desirable, meaning. as
you said, "affect the ability to investigate other solutions?" With a
working solution, others may be less likely to investigate because
Postgres-R will be our official solution. (I believe that was your
major negative point.) However, with the hooks already there, people
may be _more_ likely to investigate solutions, so there is really no way
to know.
