Any user would be able to chose between compatibility and safety.

No bogus value ever gets to a function - it always gets INT_MAX on
overflow. If INT_MAX is harmful for this function, this change

help as you could still pass INT_MAX and this change would not do
anything.
No it won't. Normally it truncates

Especially a BC break in a form of it worked before but now it

Hi!
So, the problem comes with built-in functions, which have some side
effect, which can be usefully run with a bogus value for an integer
argument. In contrast, any function which has some side effect which is
actively harmful given a bogus value would be a beneficiary of the change.
No
