No, and Rasmus examples, while being technically correct for some of
them, just add confusions to the stack. The caller, and the calls to
internals function in the caller codes, won't be affected, at all.
Please understand it. Only the library code will.

Now we can surely find other cases where we may adapt the patch or be
more obvious, but for my own sake, get over this "it will break and
change everything everywhere", it does not.

No, you do not.
