As an architect myself, I'm sure that some of the decisions I make look like bikeshedding - and maybe they are, but they're born out of a desire to make our services easier to implement and manage at scale. I do try to avoid arguments over trivia, but it's a fine line to walk. When you have a small system, the kinds of convention, indirection, and abstraction you'd see in large ones don't make a lot of sense, except when it comes time to scale out.
