No we can't. Any downstream project based off the GitHub source repo
will only see the tag on the main branch (2021b) and not get the
stability. Any project with fixed version naming conventions (eg.
Android) will not be able to adopt 2021a1. By making the choice you
have, every downstream project that wants stability is forced to make
some kind of change in the next 24 hours.

Paul, please consider that I and others consider the tip of main
branch to be considerably *less* equitable than 2021a. Until you can
accept that your definition of equity is not the only one on this list
we won't move forward.

I've already made clear that the tip of main would be utterly
disastrous for Joda-Time users. Yesterday I was forced to make a
release that tries to block adoption of your proposed 2021b, but
unfortunately the new release won't be picked up by the very
application teams that will be most affected.

There is a big difference between merging the time zones of two
African or Caribbean countries and merging the time zones of two
European countries. Whether equitable or not, the reality is a lot
more of the world's economy will be affected this time.

I am also happy to collaborate on a solution. But I sense absolutely
no willingness on your part to provide the time and space to make that

Apart from Tim Parenti, I don't think any list member wants you to
release 2021a1/2021b in the manner you proposed. Especially when there
is a low risk alternative that allows us to progress matters more
sensibly. Does that opposition really not matter at all?

I believe the mailing list has spoken very clearly - move the current
main to be a branch, reset main to 2021 and release 2021a with minimal
Samoa changes (as 2021b). Then take a long weekend and then put
forward proposed solutions.

(I have two or three proposed solutions ready and waiting, but I don't
want to publish until we are past the Samoa release).
