3d versioning?

Here’s what David said. It doesn’t say much more but may be clearer:

As versions (tips of tree) can basically fork then versions make less sense. If we go from 1-2 1-2a 1-2b etc. then in a concurrent system, it won’t work as 2b does not necessarily know 2a happened or is happening. So using hashes takes away the requirement to synchronise version numbers and allows us to have concurrent updates.
