I definitely could be wrong, the reason I posted a single patch to
upreve the version is that, I was under an impression that in each big
release (like here 5.2.0 -> 6.0.0), the incompatibility version id
should be bumped up once.
It does not look correct to me that in a big release we bump up the
version id for 10 times.

Since this is a series to fix issues in the ssi-sd, I don't think it's
practical for downstream to just cherry-pick some commits while
leaving some other commits there.
