How have you found this centralized approach to work for you? Does your org require everything be built in exactly the same way?
I’ve just joined an organization that is trying to do similar, but in practice it seems nearly worthless. Templates are frequently broken, or written in ways that expect code to be built in a particular manner without any supporting docs describing the requirements.
We centralize releases but we don't centralize builds. That would remove too much autonomy from teams.
We don't use templates for any of this. Our interface is the payload sent with repository_dispatch, a few metadata files in the repository (which we fetch) and a GitHub application that allows us to update the PRs with the release status checks.
GitHub doesn't have a great story here, ideally we would want to listen to CI events emitting from a repo and run workflows as a reaction.
The reusable story on a modular basis is better but here we're missing features that we would need to move some of workflows into Actions. Notably - Action repos need to be public.
