A 100% nuke to all leaderboards would be kind of cool if the next patch is actually stable. I have a feeling they will forget to fix some of the less mainstream glitches though.

The only reason pumpkin glitch was likely fixed is due to it being the most known glitch in the entire game.

Bundles% would probably work. A bundles% run would show the most amount of glitches.

The main problem with Stardew Valley speedruning is that no specific moment in it is particularly interesting. The only thing that would even move the audience is pumpkin glitch, out of bounds the first time, and paper items. That is about 1 interesting minute throughout a 2+ hour run.
