It’s about 5 times longer than previous releases were maintained for, and is an experiment. If there’s a need for a longer term support branch, there will be one. It’s pointless to start maintaining an 5+ year branch with 0 users and a handful of volunteers, none of whom are paid for doing the maintenance.

So yes, in that context, 15 months is long.

And that’s relevant, how? (start of the thread)

And where do you think GitHub is?

Yep. So I don’t see why they wouldn’t enforce that extra win.

…and then risk the same litigation from Nintendo, or at least a DMCA takedown, something which the settlement explicitly mentions.

Well, citing IGN:

Citra, a Nintendo 3DS emulator, will also be discontinued.

The Citra homepage seems to confirm that.

On GitHub? No. It will get DMCA’d in very short order.
