Note that I would personally never disable these checks in production, as
they may prevent potential bugs down the road, that would not have
necessarily been caught in dev.
I would rather expect PHP to bring down the cost of these checks in
production to a negligible level, as mentioned in my previous message
(static analysis and JIT).
