So if I understood it correctly, is it a way to manually especify the
SO versions?

If this is the case, several related questions come to mind:

- If the numbers that they provide can be relied upon, should we try
to use it for the other SDL libraries?

- Furthermore, should we devise an automatic way to check/generate
that (e.g. a script that we can share across our packages)?

Cheers.
