I suspect you'll have a difficult time getting this into Horizon since I'm
unsure how many people are actively working on the project. Something AJAX'y
whereby you only load the first N results and insist on more filtering (or use
of the API) for anything more would be a good start?

Based on Julia's reply, it seems pagination for the "users" API might still be a
non-starter. You could probably look to implement it for other resources like
projects and domains though. Once available in Keystone, it should be pretty
easy to add to Horizon (pagination is available elsewhere). I know Keystone is
undergoing a bit of a revival right now so there's a chance this will get more
traction...though of course you'll still need to add stuff to Horizon at a later

Horizon uses blueprints, as discussed in the Horizon contributors guide .
Creating an initial blueprint and some PoC patches might be a good start?
Keystone uses blueprints and specs  so if you want to extend this then
you'll probably need to draft a spec then the PoC patches to prove out the idea.
