* Submission review: patch apply on HEAD, no doc or test required.

* Usability review
** Does the patch actually implement that? yes
** Do we want that?

Consensus is not complete: some use case raised.

1/ regression test: not a good excuse, see [1]

2/ being able to build contrib out of tree, it is unsure it is really needed
on its own but was suggested. See [2] and [3]

Arguments against removal are new features (extension layout, more work on
PGXS shoulders, extension headers exported, clean regression test for PGXS)

** Does it follow the community-agreed behavior?

Some people voiced against the idea. More answers might be better to confirm
that this is wanted. Amul, Joe, Craig ?

** Are there dangers?

The only I can see is packagers building contribs with PGXS, but as it is
currently buggy I'm sure they can't do that.

* Feature test: it deprecates a not-fully-implemented-feature (even fully
implemented this may not be considered a feature at all)

* Performance review: not relevant (contribs may build some µs faster...)

* Coding review: OK

* Architecture review: looks good too.

The patch needs to reach consensus before commit. There is no status for that
in CF, for me current status is: 'Ready, Waiting more feedback from
community'.
