I also vote for a release. I mean, you took the time. Why not.
Side note: Anyone know how to back up the title keys file on my 3DS? Is it the file in the "keys" folder? Could I theoretically upload that file to GDrive and point my FreeShop to it?
Probably until whatever "switch" is flipped server-side, technically, they should be okay. But who knows when the change could happen -- so I'd say just stop using sleep downloads from here forward.
