IDisplayManager.UpdateEditorAsync is obsolete?

[weirdyang]

I have getting this warning in my code, but from the source code, I don't see it being marked obsolete?

OrchardCore/src/OrchardCore/OrchardCore.DisplayManagement/IDisplayManager.cs

Line 11 in 4f5cd18

Task<IShape> UpdateEditorAsync(TModel model, IUpdateModel updater, bool isNew, string groupId = "", string htmlPrefix = "");

OrchardCore/src/OrchardCore.Modules/OrchardCore.Workflows/Services/ActivityDisplayManager.cs

Line 44 in 4f5cd18

return _displayManager.UpdateEditorAsync(model, updater, isNew, groupId, htmlPrefix);
