Sure, but Linux is also on more devices than any other OS in the world.

Your statement would be more damning it Linux was a minority player or on the decline, but that's not the case.

Also most Linux machines, like phones, also contain instances of things like SEL4, often a couple of them.

And Linux... well, it managed to accumulate a lot of historical baggage for something that young. Device numbers are another example.

Nearly 30 years seems like plenty of time?

Many projects manage to accumulate plenty of tech debt in 30 months, without being a deliberate work-alike reimplementation of an existing system.. which I suspect means you're already starting with a certain amount of baggage.
