I'm trying to phase out certain grid editors in place of new ones. The problem is that removing the editor in grid.editors.config.js causes any content using said editor to be broken, showing inner JSON.

Is there a way to remove these editors from the the grid editor selection without breaking the way existing editors are displayed? It should work similar to how Umbraco set certain property editors as deprecated, which removed them from the selection list but didn't break existing content.
