Exactly! Several different sorts of folks have an interest in product architecture, and each group needs the story told at a different level of abstraction. So inevitably one has to maintain a few different flavours of the diagram and associated story.

One way I think of it is that the architect needs to market the architecture, at least a little bit. If you ask a marketing team to deliver a message they immediately start crafting multiple delivery methods to meet people where they are at. Architects shouldn't think they can somehow escape that basic requirement of effective communication.
