If a logged in user buys something, they can't edit their email address during checkout. New Customers can. Ideally, existing customers should be able to edit their contact info. This is particularly useful for allowing administrators to place orders on behalf of others.
Provide configuration to allow the contact info (emails) to display on the checkout form for authenticated users if desired.
Testing
Extend configuration to be set by role rather than just for all "always"
