Doing more allocations isn't "less work". No matter how many times you mumble "But it's just a pointer bump" the alternative was no work.

Sure, it's easier to implement this, the New Jersey style. But that's not a benefit to anybody else, so if you're not Sun Microsystems (which you aren't, Sun no longer exists) then that's not actually a benefit at all and this was a bad trade.

Which is why people have expended an eyewatering amount of effort on Project Valhalla to some day fix this stuff.
