(blog author here) That is the kind of thinking which just unnecessarily gatekeeps innovation.

There's always someone "in control" of a server. But even more important, there's always someone (or usually a group) in control of deciding which shell should be the default on an OS. And these are the people that should be reached somehow.

And Oils is just as much a snowflake as Bash, Tcsh or Ksh. All of them are POSIX compliant (though not sure with tcsh), all of them bring own additional features. But the only shell with additional features which don't suck (by being 30yo) is from the Oils project.
