We have a standard! It’s this great decentralized VCS called git. For most of the stuff integrations do, they’re just showing code or commits — both of which are readily available in a copy of the repo.

Probably the one thing that’s missing is a standardized webhook system so that your git repo storage could tell integrations when stuff changes. Though even that isn’t strictly necessary if the integrations keep a copy of the repo up to date.
