Clean out backlog of pull requests

[micpap25]

It doesn't look like there's a currently open issue for this, so:

Can something be done about the (as of writing) 553 currently open pull requests? A very large number either add features that have already been added, or can no longer be merged in without significant revisions. Clearing this backlog would make merging and organizing future PR's much easier.

I'll be flagging PR's that should be closed for attention, but I think that a maintainer of the website should go through the PR's to resolve this problem.

We’re working on completely new docs (#3308) so it’s not a good time now. We’ll go through the backlog after we ship them (or at least a beta) to see what’s relevant for the new docs and what’s not. Doing this now would be redundant work.
