    Description

      Filesystems which don't support things like append() tend to throw a simple IOE, which makes it hard to distinguish "append didn't work for some IO problem" and "append isn't implemented".

      If we add a new exception, UnsupportedFeatureException, make it the strict failure mode of such operations if not supported and patch all our filesystems to raise it, then at least code has a straightforward check. Same for any other unimplemented feature
