You’re simultaneously arguing that GitHub doesn’t restrict folks enough (“what headache does that buy us aside form more people bitching”) and that it’s way too restrictive ("Hell 50% of my PostGIS client base does not have a github account”). 

Please choose just one BS argument and stick with it.

Of course, once migration is done, ownership of new things is correctly handled. You can see the effect of this in the mapserver migration: https://github.com/mapserver/mapserver/issues/2154

> Long and short of it, since folks are basically saying "never never never", I am demotivated to complete the investigation and get the "most perfect" migration I can to show you all what it would look like. I have a migration that is slightly better than the mapserver one (dates are correct on tickets, and all the revision references are remapped to hash references) but if there's no enthusiasm for getting into that larger pool, I'm going to stop swimming and return to other, more useful work for my employer.
