If I have a bunch of

ValueSources

that do expensive things (like execute git, etc), and I want to share these across multiple plugins so that I don't have to duplicate code, as well as create multiple providers for the same thing, I had an idea to put them in a BuildService. however, it seems like if I create the providers in order to pass them to the service via params, then they get run, even if the build service method that returns that provider never is called. I had an idea to create the providers only when they are accessed via build service, but to do that, id need a reference to ProviderFactory as a param, but I don't think that is serializable (for CC). is there an established pattern here?

A ValueSource is scoped to the Build, not to a Project, so the inputs should only produce 1 outcome that will be reused/cached during CC. Edit: it is not cached across projects 🤔 A BuildService provides inputs during execution time for multiple tasks.
