No, because the HRE is fun, I enjoy the messiness. I am saying using "the HRE is uniquely decentralized" isn't a great argument for why it needs more locations than other empires, because if that is the logic, then yeah, all the major empires should function that way where the crownland is the land you hold personally and you need to wrangle your vassals into line to create modern states.
I think a lot of people are starting with "this is what I want" and working backwards to "this is why the game has to be this way." Just stick with the former, you want the HRE to be especially balkanized at game start because you think it's fun and you aren't as worried about the same fidelity being applied to other regions at game start, don't try and justify it.
Is there way more information, or just more information in sources a European can easily access? I would lean towards the latter, and that's a great example of the eurocentric focus people are complaining about.
