Suggest documenting the new parameters in integration.rst. Not a blocker - if you prefer to do this later, please create an issue.
Similarly, I suggest describing the internal workings of this PR and #2455 in the reference guide - also not blocking but should be tracked in an issue if defered.

As integration.rst is quite outdated in general, I suggest we complete this in a dedicated pass.
