As the person who brought up the "split stream" suggestion months ago,
which IIRC was liked by no one but me :-( , have we considered even/odd
versioning [1], like what node does? (tip: it's the same thing I suggested
before, just a different name :-) )

We need both:

- the freedom to break APIs (odd versions)
- a stable platform for our customers (even versions)

Perhaps we can noodle on that, and other approaches, before next week, when
some of us are able to wrastle over it in meat-space.
