I think it's especially valuable to try and be complete when doing a migration from a centralised VCS to a decentralised one; once you manage to migrate the repository once, you can then avoid any necessity to maintain servers for it. In extreme, you could just distribute a tarball of the decentralised VCS, hence all you need is the ability to distribute a tarball, which is a lower bar than maintaining servers for it indefinitely.
