This is not a package wishlist - it's a way to submit packages that are intended to be included in official Fedora repositories for review.

You'll likely have more luck getting somebody to look at packaging Mozilla VPN by asking in the Fedora Golang channel on the Fedora Matrix server, or by posting to the Golang mailing list.

Note that I personally tried packaging Mozilla VPN at some point in the past, and got a package into a state where it built and installed correctly, but the built executable crashed immediately. I couldn't figure out why, and gave up.

Hopefully someone picks up the torch, but anyone here looking for a good option in the meantime, I am on Silverblue and have been using https://github.com/NilsIrl/MozWire to happily use Mozilla VPN for a few years now:
