Great!

Do we have examples of such tools and code bases structured to
accommodate them that we'd like to use for reference, or at least for
inspiration?

+1 on that.  It would be helpful to see successful examples.  Especially ones written in C.

I can't really figure out what success looks like just from reading the descriptions.
