This is not a one-off thing.
We maintain ABI for some time (1/2 year(s)), and we expect to bump ABI.
When doing this, in size, the diff will be at least the same than what
we have here.


If you disable libraries, features etc... you get a new ABI.
What would be the reference*s* then?
Builds with default options from meson for each architecture?

Creating a separate git repo is just adding more pain to submitters
(/maintainers): they would have to submit (/apply) patches against two
trees.
