I’m starting to realise that a big part of why self hosting works is the customisability of it. There’s no financial incentive for Google or whomever to make sure process A has an interface to talk to process B because it’s a minority use case in their clientbase.

Self hosting - either someone has already had the same issue and made a plugin or I can create a shim of some description to make the two things talk to each other that wouldn’t be practical at scale.
