The key here is that a browser implementation of a CSS draft property is a snapshot in time of the specification of that property at the time of implementation. If the draft is revised, it's not the case that all browsers suddenly revise their implementations to match; not only is there a limit on engineering time, but browsers typically have 6-12mo release cycles, so implementation is bound to lag specification.

My suggestion was that if the syntax changed incompatibly and there
was a notable existing implementation, a number could be appended:
draft-image-fit2 or draft2-image-fit or such.  This is somewhat ugly,
but it retains the practical benefits without drawbacks that I can
