This is called mechanical sympathy and most architects and developers do not have it. Computer architectures encompass 13 orders of magnitude of performance! That's roughly the difference between something like a trivial function call processing data in L1 cache to a remote call out to something in another region. People often make relatively "small" mistakes of 3 or 4 orders of magnitude, which is still crazy if you think about it, but that's considered to be a minor sin relative to making the architecture diagram look pretty.
