<p class="MsoNormal"><span style="font-size:12.0pt">Speaking for myself, I have no hostility towards GitHub, and there is no GHC-HQ bias against it that I know of. If it serves the purpose better, we should use it. Indeed that’s why I asked my original question.
I agree with your point that data may actually be safer in GitHub than in our own repo. (And there is nothing to stop a belt-and-braces mirror backup system.)<o:p></o:p></span></p>

I think this is a question of perspective: Having the master repository on GitHub doesn't mean you are in immediate danger or lose your "family jewels". IMHO it's quite the contrary: I'm e.g. sure that in case that something goes wrong with GitHub, there is
far more manpower behind it to fix that than for any self-hosted repository. And you can of course have some mirror of your GitHub repo in case of e.g. an earthquake/meteor/... in the San Francisco area... ;-)<o:p></o:p></p>

This is by no means different than saying: "I want to run 'validate' in the commit hook, otherwise it's a big mess." We don't do this for obvious reasons, and what is the "big mess" if there is some incorrect submodule reference for a short time span? How is
that different from somebody introducing e.g. a subtle compiler bug in a commit?<o:p></o:p></p>

Because the whole repository structure is overly complicated and simply hosting everything on GitHub would simplify things. Again: I'm well aware that there are tradeoffs involved, but I would really appreciate simplifications. I have the impression that the
entry barrier to GHC development has become larger and larger over the years, partly because of very non-standard tooling, partly because of the increasingly arcane repository organization. There are reasons that other projects like Rust attract far more developers...
