I don't have much of an opinion on moving ITK to GitHub, but I'd like to
address some things Andras mentioned about GitLab and VTK.

I am not aware of any plans to move VTK to GitLab or even any discussion of
doing so.

The first few versions were indeed a bit slow, but new updates come out
regularly, and the speed is quite snappy. I use it both from within the
Kitware network and outside the network and haven't noticed a difference.
