Well, hosting everything with a service that is backed by a company and over which you have no control was never a good move. See how Rainer Gerhards hosts his rsyslog (http://blog.gerhards.net/2013_12_01_archive.html): one canonical repository, and GitHub as a peer. Given git's distributed nature, there can be as many clones in as many services (Gitlab, BitBucket, others) as maintainers deem sensible.
