I don't see this being a thing for this game, since the borders between glitchless and glitches are somewhat fluent and it would be very hard and arbitrary to define what would be allowed and what not. But for getting into the game (I don't know how much practise do you have yet), you wouldn't do skips anyways, and only eventually adding them later on. That being said, you can still get a really decent time without doing any major skips, so just go for what you like
