This statically enables #22313 for 18.
We've had it muted in www for a while and there's been no hits. So this pattern seems extremely rare.
Arguably maybe we should backport it to warn in 17. And then make 18 throw instead. Then we can change the API in a minor.
But if 19 is fast follow then we might as well warn in 18. And batch the breaking change with other changes in 19.
