It would be too painful to move D to Gitlab or another medium?

My personal projects have been converted from CVS to Subversion 
to Mercurial to Git over the years. And from SourceForge to 
Google Code (RIP) to Bitbucket to GitHub. But always at a point 
where that seemed like the natural way forward, when the benefits 
seem obvious. I think it's the smaller projects that have to pave 
the way, not the large ones that involve hundreds of 
contributors. An official mirror makes more sense to me at this 
point in time. But I'm also not a D contributor, just a user.
