IMO this is kind of the tradeoff. In 140E we do touch on virtual memory (w/ coherency handling on our specific ARM core), FAT32 "from scratch", etc. but it comes at the expense of prerequisites. There is a lot of effort to "minify" the labs to their core lesson, but there is an inevitable amount of complexity that can't (or shouldn't) be erased.
