It will vary per extension. For some it will be none. For others it
will be 'some' time for each place the extension converts a PHP value
to a string. Maybe a couple of hours for the first one, less time
after that.

Immediately nothing.

Eventually, when a __toString() method throws an exception, and the
extension doesn't check for an exception being throw, bad things will
happen.

But in my opinion, if people don't understand the implications of the
RFC even after reading the details in the RFC and this thread, then
this probably is an RFC they should skip voting on.
