GitHub does provide some automatic redirects when you use their system to change your user name, repository name, or transfer the repository to another account.
However, it is a good idea to still make the request on the issue tracker in case the redirect stops working at some time in the future.
That's correct. This is done periodically by library authors and there's no problem with it. There is a bit of a delay, since it's a manual process, just so you're aware in advance.

I don't want to spam the issue tracker if there's a better way to do this.
I'm now working with a larger group so it makes sense to use a single, shared account, rather than lots of individual ones with cross-forks, pulls, etc. But it also means updating my Github client, lots of testing, etc, etc. Fortunately it's only five libs.
