If someone takes one look at one project and decides to copy it’s architecture word for word, then it’s on them. Not on the person who built an open source project, for whatever reason, and put it out there for the world.
It’s not your architecture to architect. If you want to build your own service to show best practices, then go for it. You weren’t there to make decisions, you don’t know of the reasoning behind them, and it seems ludicrous to backseat architect with context, let alone without any amount of it.
