Looks good but please test and report back as we dont have automated testing for integrations yet

@claudijd did you manage to test this code? It will be great to approve this PR, but we want to make sure everything works before we push things to master.

@dekelb I wasn't able to test, and I no longer needing this patch upstream. That said, I think there is value leaving it open as a consideration for improvement, should someone have the ability to confirm or ammend it's viability.
