I don't disagree with any of the points you have raised, I was just checking if any inefficiencies(to the degree that there are any) are noticeable and/or something to genuinely ponder when thinking about the tradeoffs between cost, performance, maintenance.
I'm certainly not insinuating any kind of deal breaker, I am genuinely interested in internal hubs, so appreciate the feedback from those who ride them.
