Summary: Previously we added a deprecation warning for delayed scaling in v0.9.0. Now that the branch cut for v0.9.0 has passed, we are deleting delayed scaling from the codebase to simplify the code. Motivation: 1. delayed scaling adds a lot of complexity 2. we still don't have any customers for delayed scaling, since people prefer to optimize for higher accuracy from dynamic scaling If a need for delayed scaling arises in the future, we can bring it back to a prototype folder in a way that is decoupled from the dynamic scaling code. Test Plan: ``` ./test/float8/test_everything.sh ``` Reviewers: Subscribers: Tasks: Tags: ghstack-source-id: 8d8b801 ghstack-comment-id: 2674970350 Pull Request resolved: #1753

Summary:
Previously we added a deprecation warning for delayed scaling in v0.9.0.
Now that the branch cut for v0.9.0 has passed, we are deleting delayed
scaling from the codebase to simplify the code.
Motivation:
prefer to optimize for higher accuracy from dynamic scaling
If a need for delayed scaling arises in the future, we can bring it back
to a prototype folder in a way that is decoupled from the dynamic
scaling code.
