When change field type from Formula to something else, need to uncheck the "Read Only" field

This has happened to me several times that the field is read-only and it takes a lot of investigation (or one of your excellent support agents) to identify the issue. It would be nice if the app checked and unchecked the read-only option when you change field to/ from formula (if the field it changes to is in fact something that would be read only by default).
