Yes it really cannot emphasized enough that the legacy filesystem system interface with it's too-simple 1970s origin and then far, far, far too complex decades of duck tape is a disasterous albatros.

C.f. What linus is saying in https://news.ycombinator.com/item?id=21673372 except turn it around. When an interface has devolved into two sides hating and Postel's-law-enabling each other ad infinitum, and a statement like his is actually justifiable, it's time to close up shop and move on. Nothing good will ever come from POSIX-like storage ever again, and any storage system built around it is doomed to be a mess of too many layers and also too many layer violations. Utter hopelessness.
