I'd like to see the category name for movies dominated by a single glitch specify the glitch in the category, e.g. DOS NetHack "memory corruption glitch" vs. DOS NetHack "minimum turns, no memory corruption".
In practice, there tend to be only two (or three, depending on how you count) sorts of glitch that end up dominating a game enough to require a new category: memory/save corruption glitches, and out-of-bounds glitches that lead to skipping most of the sequence of the game. Instead of "forgoes time-saving glitches" (which ones?), I'd like to see "corrupts memory" and "forgoes memory corruption", "corrupts save data" and "forgoes save data corruption" (we already have these two, so no change is needed there), "goes out of bounds" and "forgoes going out of bounds". A good example of why this sort of thing is necessary is in the Generation I Pokémon games, to distinguish the categories in
[1702] GBC Pokémon: Yellow Version "save glitch" by p4wn3r in 01:27.23 (save corruption) from
[1700] SGB Pokémon: Red Version "warp glitch" by p4wn3r in 41:02.38 (arbitrary memory corruption) from
[950] SGB Pokémon: Blue Version "trainer escape glitch" by primorial_soup in 1:18:58.78 (out-of-bounds). Note that all three of the movies are tagged "heavy glitch abuse"! At the moment, 1700M isn't tagged with a branch name, nor is 1702M, which might leave the viewers wondering why they take such different routes in such similar games. I'd like to see 1702 marked "save corruption glitch", and 1700 marked "memory corruption glitch", to distinguish the branches. (Out-of-bounds is more normal; I personally consider 950 the current "normal" category for Pokémon, and would watch a no-out-of-bounds run as well, although I doubt it would be different enough from the other runs to be interesting and publishable.)
I agree with the OP that "glitched" by itself is pretty unclear, especially as it's used inconsistently. Instead of trying to imply "more glitched than" or "less glitched than" or whatever (which will probably depend on the order in which the movies were originally published), why not say exactly what the category actually is? (I also say this because I know there are people who enjoy watching entirely non-glitched TASes; I like both glitched and non-glitched versions, but people who want glitchless runs have a lot more than the runs in
the "forgoes time-saving glitches" category to look at, because there are many games with no known major exploitable glitches. (Keeping with the Pokémon example, Pokémon Ruby/Sapphire, while there are a few known glitches, don't have any known ones that save time at the moment. No doubt TASers are working on correcting that, but for the time being, a third-generation Pokémon TAS is going to be glitchless just because that's fastest.)
