### Target Plan Acceptance Date

### Earliest Open edX Named Release Without This Functionality

Pages will be available via opt-out in **Teak**.

Pages will be fully removed in **Ulmo**.

### Rationale

This technology should be removed because it is fully replaced by the authoring MFE. Keeping the html files and rendering code for the legacy pages increases code debt as it will obsolete.

### Removal

### General removal

- `cms/djangoapps/contentstore/toggles.py`, delete lines [238-554](https://github.com/openedx/edx-platform/blob/master/cms/djangoapps/contentstore/toggles.py#L238C19-L554)
- `cms/djangoapps/contentstore/rest_api/v1/serializers/course_waffle_flags.py`
- `cms/djangoapps/contentstore/rest_api/v1/views/course_waffle_flags.py`
- `cms/djangoapps/contentstore/rest_api/v1/views/tests/test_course_waffle_flags.py`
- `cms/djangoapps/contentstore/utils.py`, delete lines [290-429](https://github.com/openedx/edx-platform/blob/master/cms/djangoapps/contentstore/utils.py#L290-L429) and [444-506](https://github.com/openedx/edx-platform/blob/master/cms/djangoapps/contentstore/utils.py#L444-L506)

### Page specific removal
*For each of the pages' html files, the imported js factory should also be deleted

### Deprecation

_No response_

### Migration

_No response_
