If you are arguing strictly about not knowing what to write on the
documentation, let's move the discussion towards whether it should be
defined or not.

Right, and therein lies the problem. No one has ever defined this behavior.
As such, one cannot document what has never been defined.
What you're describing is UNdefined. Undefined things cannot be documented.

It's undocumented, because it's considered undefined behavior. PHP arrays
implicitly store the number of elements internally as an unsigned 32 bit
integer (regardless of architecture). This means that (technically) you
can't create an array with more than ((2**31) - 1) elements (or
