Remove APIs marked as deprecated for removal

[jhoeller]

Overview

In 7.0, we should aim to remove all classes, methods, and features marked as deprecated for removal (as of 6.2.0 in November 2024).

Any remaining deprecations (or new post-6.2.0 deprecations) are expected to stay around for 7.0.x at least.

Can you assign to me

Hi @learnconcept,

A task like this is something we need to address ourselves and not until we have branched for 7.0.x. In addition, it often requires actions from several core team members.

In light of that, this is not an ideal-for-contribution type of issue.
