As of now if we override an Edit button, the available options for a Lighting Experience are as below:
1. Either use Classic Override
2. Use Lightning Component
It would be a nice feature if a third option was available, similar to the option available for Classic - "No override (use default)". This would have allowed to skip the Classic VF page override if any and just utilize the standard behavior in Lightning Experience. As of now the only option to do that is to create a custom component and use it, which just would have been not required if the option was present.
