It is tricky because of the situation between:
* apt.llvm.org with three branches
* stable packages (ex: 10.0)
* rc packages (ex: 10.0.1 rc4)
* snapshot from the VCS (ex: 11~++20200701093119+ffee8040534-1~exp1)

And you can have llvm-toolchain-9 from Debian official, -10 for apt.llvm.org and -11 from Debian experimental.

I need to make sure that the expected behavior is what users are getting
and that the upgrade path still works (upgrading from version x-1 to x).
Changing this is always a lot of work as it requires synchronized uploads/updating scripts
(not mentioning the potential regressions)

Anyway, I am not sure to see what your point beside consistency in Debian (note that, AFAIK? there isn't any policy).
I have been using that patterns since the svn => git upstream migration (it was similar with git).
And at the end, Debian Stable only ships with clear versions like 10.0.1-12.
