This was found while the Publisher Squad was doing some investigation around Studio date settings.
This field used to be used to set a start time like “Winter 2020” instead of a specific date field. But at edx.org at least, neither marketing site (Drupal or Prospectus) uses it. It might be used in some display pages on the LMS though.
Because it could be used on the LMS, this might want a DEPR? I dunno.
Ideally the field would be deleted (it’s really not used for anything), but if that’s socially or technically difficult, marking the field as deprecated in studio might be a good backup plan.
Delete the Course Advertised Start advanced settings field . See the slack conversation  about this for context on how it is unused. This field is not supported in either drupal or prospectus, and has been deprecated for some time, but never communicated.
Mention to PCs that you’re doing the above, just as an FYI. Gerrit might also be curious, but only because he’s been involved in some discussions around us not using this anymore.
Delete the data in the model behind these fields too?
