> 3. release project.0.3.1, keeping project.0.3 unchanged

The problem is that `project.0.3` will be broken for ever, as well as all
dependencies that depend on this particular version.

Maybe there is actually some misunderstanding, and we're talking about
different things. Just to clarify, are you going to go
through opam-repository and update all archives of old libraries (e.g.
sexplib.7.0.5, sexplib.108.00, ...) and remove `<library>.syntax`
findlib library from it? This is what I'm afraid of. And this is what I
name "retroactively".
As according to the PR there is nothing like this. If all old archives will
be still available, then it is perfectly fine.

This is what I'm proposing.

Yep, but it is not a problem to me to fix it. I'm just wondering are there
any more packages, that provide build systems, that can have such problems.
Maybe just grepping the opam universe will help in answering this question.
