I still think there are a plenty of reasons to support POSIX in many places. As someone who's been running fish for a while, I can appreciate the common ground it provides across the current UNIX ecosystem, but it's not like translating a bash script to fish is impossible. There should always be a supported standard, but there should be nothing forcing you too it. This is the freedom we need to demand of our OSes.
