Yep, that is cool!

Well there's two things conceptually; PAPR is a way to
test pull requests, but it's pretty integrated now into
our Homu instance, which adds quite a bit of logic
on top of github's default flow:

And in particular for us, I personally really, really dislike merge commits
for single commit PRs.  It makes `git log` much harder to read.

Compare e.g.:
with your typical github project that uses merges;
we also have pretty stringent commit message requirements,
(IMO) comparable to Linux kernel core quality;
is a good random example of a 2 paragraph explanation
for a 1 line change (written by a contributor matching our standards).

Homu is definitely wedged awkwardly on top of github's
current review flow; there's no doubt we're "fighting"
github to an extent.  But the results for me are very
much worth it.  

I'm aware other people feel it's easier to just work with
whatever Github does by default; e.g. the
project made that switch when they moved to Github.

The Kubernetes (and OpenShift) projects use [Prow](http://prow.k8s.io/)
which hass some similar logic, although it generates merge

There's some other discussion related to this here:

I'm very interested in share at least some code though!
Having things in CentOS CI seems like a good start?
