The assignment improvements propose relocating the current items within the grading options section to various parts of the UI on the assignment submissions page. These items are currently part of the mod_assign_grading_options_form class as form elements. As part of the migration process, starting with the workflow filter in MDL-82508, these elements have been removed from the mod_assign_grading_options_form class. However, although it's unlikely, this class could potentially be used by external code, making the "aggressive" removal of these form elements a possible source of unwanted behavior elsewhere.

To ensure that there are no risks of introducing any issues, we should:

1. Revert the removal of the form elements in the mod_assign_grading_options_form class.
2. Introduce a new temporary class as a copy of mod_assign_grading_options_form specifically for use within the assignment submissions page and to resume the gradual migration of its form elements. Once the migration is complete, this class will be removed.
3. Deprecate the mod_assign_grading_options_form class once the temporary class is introduced, as it will no longer be used in core.
