I guess it is more about the fact that it is very hard to learn new magic spells for unicorns with cutiemarks not suites for, well... magic.

And when pony becomes alicorn it's just give her/him(?) some "boost", so they can learn magic a bit easier/faster than unicorns. I think that's how Celestia/Luna/Cadence can wield such strong magic spells even if it is not related to their cutiemarks at all. Though can't say for sure about Celestia/Luna because their history is mystery and the very fact that they are not like others alicorns.

But Twilight is kinda unique because of her cutiemark +alicorn status.
