"Your "customers" should not be expected to go to have to go to that level to tell that 0.1.0 is not identical to version 0.1.0. They certainly do not come to the project expecting to need to do so."

This is code in active development to meet support criteria that shift from day-to-day in VisualEditor (and other potential users). "0.1.0" is a standard flag for "very early code, don't expect things to continue to be similar, don't build off this". I'm sorry that this semantic meaning eluded you. Arguably I shouldn't have changed the "status" from "experimental" to "beta", but it's not ready for third party dependency development.
