Why has the class FiniteElement been removed?

Upon switching from `2024.2.0` to `2025.2.0` I realized that the class `FiniteElement` is now only available in test/utils.py, and therefore not accessible from outside.

Why? What is the idea here? Should one make a copy or how to solve this?

Also, the function `extract_arguments_and_coefficients` suddenly disappears without prior deprecation warning. It was not marked
with a leading underscore, so it's ok to use from outside of the ufl module.
