I just spent a few hours typing in a list for restrictedEdititions.json from https://mtg.fandom.com/wiki/Set and I can't even be sure I didn't make typos or get a letter and number mixed up, like 1 and l ... or 0 and o.
I wonder if the devs might consider distributing a text file where the set names can be copy pasted into json if the user wants, so every individual doesnt have to spend an hour or two googling and typing.
The text file could just sit for reference or be at the end of a readme. Too bad comments aren't allowed in json or we'd just uncomment lines. I guess XML does have one advantage.
