How to build and design blocks for consistent dev and user experiences

We should have a good guide for building blocks so that they:

• Provide a nice user experience that is consistent with Core design principles
• Make it easy for theme authors to integrate with them
• Favors smaller pieces that can be integrated into patterns
• Integrate with Core design tools
• Use Core components as much as possible
• When a binding, variation, or style variation would be better

Basically, this should be a sort of "dos" and "don'ts" of block building with perhaps some tips/tricks thrown in. Mostly, I'm just throwing out some ideas at the moment. Please contribute to the discussion.

This idea came out of a discussion around WooCommerce and creating a consistent user experience. CC: @ellenbauer
