[meta] talk about design goals with customer

[benrobby]

Story

As a user/developer I want to justify my design decisions with rules and principles we agreed on with the customer.

Description

Why:
(What value does it have? For whom?)
What:

• [ ] how much should we implement and how much should be up to swa students
• [ ] opt-in use?
• [ ] how easy should it be to understand the code as swa student
• [ ] how much do you need to know about our implementation when using it
