Can't you just use { } instead of these?

Ditto

More { }

These should be false

Could this be a map, so we don't need to iterate?

Would NeverDestroyed work here?

Yup.

Nope. Can't use initializer lists in the ternary operator.

"Initializer list cannot be used on the right hand side of operator '?'"

Yup.

There's lots of "integer-as-bool" in this file. Should probably be cleaned up at once.

A cursory glance at all of our call_once initializers suggests we do "new", "malloc", "CFCreate...", "...alloc] init..." inside without bothering with neverdestroyed.

There's definitely no static initializer problem here, so I'm not sure what the point is.
