Usage of a more concise, powerful and clean shell language is much more
suitable as a point when bringing forth an argument of there being less
bugs.

I'd say that the amount of bugs in the underlying implementation of a
shell almost does matter nothing when compared to the horrors of
hacked-together shell scripts that try to be as "basic" as possible,
trying to be as "compatible" as possible with anything, exchanging
cleanliness and expressiveness for horrible Debian init script-style
code.

Saving a pseudo-array into a string just to manually reconstruct the
pseudo-list when the occasion arises to access a specific element is
just one example of what awaits people who ignore the benefits of Bash
arrays when they could have had them just by using a different shebang.
And nearly everybody who has to write this quickly will do it wrong.
