It's logical of course, but I see the irony. Or maybe it's not irony, nobody really knows what irony is, but it's mildly.. amusing? It makes half my face smile in a manner similar to but not quite like a smirk.
Definitely not 'expected'. I like the mailing list bug tracking more than having that on git{hub,lab,whatever}.
git makes it even possible to host a repo on multiple git* hostings, but apparently nobody came up with a successful distributed pullreq/issue tracker yet.
