Yeah, I suspect the grandparent comment meant that spellcheck (and perhaps other tools, like you listed) should be standardized. And thanks to the big cos (Apple and Microsoft) doing full vertical integration of their stack and calling it their “operating system”, that term is increasingly getting used for something more than just “the thing that operates your computational resources and safely exposes their APIs for developer use”.

That said, it would be interesting to see more actual OS development that innovated on supporting/encouraging more standards, without getting too proprietary or centralized.
