New Comment:
This is project personal I started more three years ago, so it's no big deal for me. I just
revert back to PHP7. I only wanted to checkout the performance improvements.
Even though, it's unlike to be reverted, I would like to add this issue to the internals
mailing list. I don't see why making more things more restrictive is an improvement. How do I
bring it up to the internals mailing list?

you don't jump to a x.0 major release lightly and especially you don't jump from 7.0 to
8.0 unless you are asking for troubles

I don't think so. If you strongly feel that this "feature" should
not have been disallowed, please raise that on the internals
mailing list, although I consider it unlikely that the change will
be reverted.

In this case it has been only *one* year.

there was 7.1, 7.2, 7.3 and 7.4
sorry, but nobody can help you if you skip 4 major releases
there is a reason to introduce warnings years before

Thanks for the quick response. I was upgrading from PHP7.0 so didn't get any warnings. By
crash, I meant the my script was crashing.
So, is there any work around other than explicitly instantiating each variable. This seems like a
big inconvenience, special if one relied this behavior for API development.

That code already issued E_WARNING as of PHP 7.4.0[1], and the
warning was promoted to an Error exception according to the
respective RFC[2]. It is also documented as backward incompatible
change in the migration guide[3].
Note that an Error exception is not a fatal error per se, and that
even a fatal error is not a crash.
