I'm currently developing an "experimental" piece of software, i.e. I am not even sure some features I want to add are possible, meaning I had to rewrite it a couple of times (and won't be the last). Having strict versioning, pinning, and documenting everything before it reaches a semi-stable state would discourage me from developing it altogether. I agree with the approach they are taking, keep the disclaimer, put it out there, get some visibility to find early adopters and contributors and stabilize it. A year from now people will have forgotten about this thread and will see it a new and stable framework.
