I believe we should have 100% Glitchless, starts and ends the same way as as the normal any% speedrun but to do it, you need to complete all the missions and get all the paints, none of the yellow boxes containing scrap will count due to them spawning randomly. I have been working on a speedrun for it and feel like it should work
Sound like a pretty solid idea its really that there isnt many glitches other than the jump boost from jumping off the train
There's also the "skip" when it comes to getting Bug Spray, since you complete the mission before it begins. Same with the rocket launcher, if it tickles your fancy. But generally I wouldn't classify either of those "skips" or the Train Boost as glitches rather than minor exploits. That said, I do think a 100% run category should be present.
The mods said in the discord that it will be added soon (hopefully), they are just working everything out with it. But it will be All Missions, All Upgrades, and All Paint cans.
As said, there's no real difference between Any% and Glitchless bar train boost. Also, 100% is now a thing.
