One problem with installing that in contrib/ is that it would require
more maintenance as a stable and "released" module. The aim of this
module is to be more flexible than that, so as it is possible to
extend it at will even in the back branches to be able to implement
features that could help with tests that we'd want to implement in
stable branches. I have mentioned that on a separate thread, but
adding more extension maintenance burden while implementing complex
tests does not sound like a good idea for me in the long-run.
Perhaps we could consider that as an exception in "contrib", or have a
separate path for test modules we're OK to install (the calls had
better be superuser-only if we do that). Another thing with the
backend support of injection points is that you could implement your
own extension within citus, able to do what you mimic this in-core
module, and get inspiration from it. Duplication is never cool, I
agree, though.
