Yes: and you will still be able to do that. No one will take that away, so
continue to use that where it is appropriate.

All input from a form needs to be validated before use; failure to do that is,
unfortunately, common and leads to issues. If this helps remind people to do so
then it can only be good.
The first listed here is ' Improper input validation':

They will have it blow up when it first runs, fix the bug (add a cast or
something) and move on. I think that it is an insult to PHP coders to assume
that they will not be able to cope. They will scratch their heads the first time
that it happens to them, google/... & learn.
The benefit of this is fewer issues in libraries. It may also help by catching
user/coder errors earlier and so make their life easier.
There is trade off bet
