It seems we pass this into ProcessorStateManager only -- let's move the variable, and hardcode true for now.

I think we only use this in one place, and it should be possible to remove the variable (and it's usage) completely, in one go

This class is more complex. Might be better to split into a different PR, as it required more cleanup. Doing a partial cleanup for a single class, is not a "clean cut" and make reviewing more complex.

I would not disable this test, but rather clean it up directly. Or exclude StoreChangelogReader from this PR.
