When converting something which has currently silently ignored (part of its)
parameters to a ValueError Exception, you should add an E_WARNING phase to give
developers a time window to fix their code.
Example:
mkdir("foo", 070555)); # Currently does the same thing as 0555
The E_WARNING phase enables developers to catch writing 555 instead of 0555,
but it allows fixing the code without being a blocker for upgrading to PHP 8.6.
