Ultimately the definition of what is or isn't a glitch isn't the most important question because it's often such a fuzzy question. Like how some competitive gaming communities often have informal rules to keep competitive play interesting by banning specific overpowered mechanics, the more important reason for allowing/banning specific glitches or types of glitches is to keep the competition interesting for speedrunners and viewers. Obviously some games are more interesting than others to speedrun, but like in the example of Zelda: Ocarina of Time, by ruling out specific glitches you can make sure that speedrunners continue to explore the surface area of the game rather than only trying to optimize a specific glitch with outsized impact on run-time.
