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.
