Define a process for design docs

Writing design docs should be encouraged, as a way to discuss the design of a feature before its full implementation, and to provide documentation and history about the change. We currently don’t have anywhere defined to hold design documents, and thus there have been two posted to the forums. We should attempt to solidify what the expectations are around writing design docs, but at minimum, have a place to put them for if/when they are written.

Start by reviewing the issue body and the two design documents previously posted to the forums. Define the expectations for writing design docs and choose a durable place to store them. Done means the process and storage location are documented and no longer depend on forum posts.
