Hi Yves-Alexis,
yeah I expected this to be a more discussion-worth one.

I contacted a few more people and it turns out that those that "really
really" need
it e.g. for FIPS create an own checksum checker independent of the
integrity-test plugin.

Change might be something like the following on top on the other enablement
