How about something for competitions to parallel the "new club" option that extinct clubs have? (I.E. "new competition") Personally I'd quite like it if I wasn't being told that my team won the Carabao cup in 1976, for example. I actually prefer to just edit all competitions to their non-sponsored names but even they change over time, so it's inaccurate to say that Sheffield Wednesday won the Premier League in 1904, for example, since it was nearly 90 years away from existing. Alternatively/also there could be an optional "sponsored/official name" or "generic name" field alongside the "name" and "short name" fields for competitions in the editor.
