Description

This would be nice for things like being a dependency of the druid-derive crate.

How I would do this is to make a feature in druid, 'shell', that is enabled by default. With this feature missing, only essential traits would be available, like Data and Lens. I suspect I will also want this for other things down the road, like cargo-druid.

Research direction
Investigate druid's Cargo.toml to understand existing feature flags and module structure. Examine the druid derive crate's dependencies to identify which parts of druid it requires. Propose a design for adding a 'shell' feature that gates the shell module, ensuring essential traits like Data and Lens are always available. Consider any breaking changes or conditional compilation needed.
