After reading through this thread as a whole, I¹d like to summarise my
thoughts so far:
* I've noticed all these discussions revolve around existing people using
the API, and seem to ignore that most new users of the API don¹t care how
it used to work, and just want the full feature set without having to
* While I was reading the thread, I realised how much I hate calling the
client a client, I don¹t think we should think of it as a client (like a
messaging or mail client) because it distances it from the actual API, I
see it as a python API hook and as an API command line interface that you
would build clients with. The level of abstraction should be just enough
but not so much that it feels like a separate thing from the REST API. So
if we solve the problem for the REST API then I think the python and
command line should expose it in the same way. And I personally feel that
explicit is the way forward, and if you don¹t specify a version we should
error, provide no default, and no fall back, for those who don¹t want to
use a specific version or are happy with whatever they are given, we
should provide keywords that can be given instead of a version such as
³latest², ³given" or something to that effect. In this situation everyone
knows what they are getting.
