It is not hard to critique. The hard part is finding how to change while moving existing ecosystem and preserving all the use cases people depend on. I expect there is a reason Arch Linux symlinks to /usr/bin and not to /bin: $ ls -l / bin -> usr/bin lib -> usr/lib lib64 -> usr/lib sbin -> usr/bin $PATH is configurable and allows several directories. One needs something like Plan 9 namespaces and union mount to replicate, for example, rbenv: ; cd foo ; bind -a /ruby2.6/lib /lib ; bind -a /ruby2.6/bin /bin Real world analogy: we are not perfect as species, but let's spend our time where and how we can improve instead of speaking of "garbage" in our DNA and how it would be great without it.
