I see that using other branches through `git checkout` is not yet present in the wiki. I will try to add something along the lines of what I wrote here about trying out other people's changes.

You can delete remotes as easily as adding them.
More recently, GitHub has provided finer grained control over pushing to specific branches in a given repo, and the MacPorts committers could choose to restrict pushes to their own major development branches while still allowing all users to create new branches on the main MacPorts repo. This might significantly lessen the number of remotes. However, I doubt that is the path that is desirable, because it allows too many people opportunity to screw up someone else's work (accidentally or on purpose).

Permissions on each fork can be set by the owner of the fork. The starting permissions are those you indicate.

The second non-committer would commit to their own branch and push to their own fork, then file a pull request from their fork to the 1st non-committer fork. An example was
It no longer appears as a clean pull request of a few commits because I ended up rebasing my branch to be able to merge it into the main repo, as there was a takeover of the pull request as

Presumably whoever hits the merge button (or merges at the command line) reviewed the code. GitHub has also recently formalized pull request reviews.

Part of being ready includes having documentation about how we'll perform the tasks we need to perform on GitHub, so people who know how to do that should definitely contribute to the documentation, and people should ask questions about things that aren't explained in the documentation.
OK. I went looking for it, but couldn't find it. Hopefully lack of documentation is not the show-stopper for converting to git, as the best way for developers to realize what is missing is by using git and GitHub.
