I tried creating a PR for aws/aws-sdk-php regarding the implicit nullable type which adds a lot of deprecations in this Test Suite:

• fix: PHP 8.4 deprecations with implicit nullable parameters aws/aws-sdk-php#2995

It was closed because it was regarded a breaking change. Do you have any way to talk to them or would you try another PR?
(This would not really be a blocker, but would result in many deprecations)

PR was merged, after some discussions.

We are identifying which dependencies need a new version to be compatible with PHP 8.4. Some large projects might need extra work and probably wait for the beta/stable release of PHP 8.4 before making those changes.
