And your point is ?

The shell is something that usually ends up invoking other programs, it provides control
and allows you to string programs together (eg pipes) to do what you want. To talk
of a shell script that does not invoke other programs is an unusual view. Yes you could
perhaps write something entirely in shell (using its built ins) but that is not how
people use it.

Your view on the definitition of The Environment is just plain wrong.
