If this was normal semver, it would be:
bis-draft-00: 2.0.0-1
bis-draft-01: 2.0.0-2
etc. ("+" and "-" have special meaning in semver).
One problem though is that when the -bis work starts, it might not be
clear if the end result (published RFC) will be NBC or BC. And this
might change back and forth during development of the I-D.
I think it quite clear that such a label should not be used in I-Ds.
