Does it make sense to lower the repairability score because I can't replace the L1 cache? If the answer is "no", then what is the difference between an L1 cache replacement and a CPU replacement on a fully integrated motherboard (like Apple's new computers)? The answer in my mind is one of convention. Perhaps the solution to this is to enshrine the Von Neumann architecture as a legal standard. But this solution seems like it could limit innovation.
