If we can do away with some non-value-added and buggy code ... then I'm +1.

Subject: CLI built-in commands
While working on
https://bugzilla.redhat.com/show_bug.cgi?id=824129
I spent some time thinking about the problem. I concluded that there
is a bigger issue at hand than just parsing quotes incorrectly.
CLI code is JavaScript with the exception of a handful of built-in
commands. So we have the majority of code that is written and
executed as JavaScript, and then we have a small fixed set of
commands that executes as Java. Because of this we have multiple
layers of parsing code. These multiple layers of parsers have led to
this bug as well as
bug
813912, and others. To make things even worse, not all of
these built-in commands are available in batch mode.
I want to propose that we do away with these built-in commands. The
functionality provided by the built-in commands should be
implemented within the framework in which users operate; in other
words, the functionality should be exposed via functions and methods
of objects that are available in the script bindings. In so we
doing, we can eliminate most if not all of these buggy parsing
layers, provide a uniform and consistent syntax, and take better
advantage of the features that JavaScript has to offer (if we so
choose). I do not see any value add in these built-in commands as
opposed to providing the same functionality in JavaScript, whether
that comes in the form of actual JavaScript code or as exposed,
native Java objects.
