Heh. That's one of my favorite quotes too :)

This again depends on the protocol. Since GraphQL is based on an object
model, it's pretty uncontroversial how to find the classes. E.g. a
Scheme API would have an Implementation class, a SRFI class, a Report
class for RnRS (or a combined Document class into which both SRFI and
RnRS fit). A Package class for libraries in package managers like Akku, etc.

Those again have straightforward queries: get all implementations, get
implementation by its id ("chibi", "kawa", etc.) Then various search
queries (e.g. list all packages with "xyz" in their name).

With REST it's more complex because you have to also design the response
formats, which are the hardest things to design (and the more time
passes, the harder it is to keep them clean).

I'd leave it up to the people writing the clients to figure out how to
best work together. People usually know what works best for them, and
it's different for everybody. So for example, if one person is most
enthusiastic about making an Emacs client, and another about a CLI
client, then they can each work on those clients and find a way to
communicate that is the best match for their personal styles.

It's definitely nice if clients can share code, but there are times when
code sharing gets in the way (by slowing down development, or if the
clients need almost the same thing but with some variations, and the
variation makes communication slow or code complex). I think the best
way to do this is that people start writing the clients, and then they
discover what makes the most sense. They can always be refactored later.

For me, the overarching concern is that I've been in many projects where
lots of time is spent debating things that not based on any field
experience. It's faster (and usually more fun) to gain real experience
as fast as possible by trying things. Often the results are surprising.
Software is so complex that the right solution or approach is usually
not obvious beforehand. So for the most part, I'd be in the "code wins
arguments" camp.
