It doesn't mean you have to use it, just that it might be used instead
of implementing a manual check in every function/method callers, or,
alternatively, in the function/method itself.
Being done at runtime by the language will for sure not be worst for
performance than doing it manually in pure PHP.

Sure! Hence why *if* this is taken into account, it should really be
done the same way as it is done for input parameter hinting, to not
introduce what we already don't want there.
