It's also been fairly easy up to this point, but I've been gone a lot and generally haven't been caring all that much, so I'm starting to get confused on certain things.

No, those conventions are there for a reason. Remnants of analysis (analysis is the math subject concerning itself with proofs in calculus and functions).

If you wouldn't use a limit, then what you're doing doesn't technically make sense anymore, and in more abstract cases you'd run into trouble. It's not really a convention, it's just a technicality which purpose is obscured by the fact that the proofs behind most calculus theorems are much too difficult for high school math.

Defining an indefinite integral like that also help with forming an intuitive idea of the concepts.

I know it may seem like mathematicians are a bit anal, but if we have to be.
