Oversimplifying somewhat…

Pushd/popd are really designed for interactive use rather than for
scripts. Hence they remind you of the stack's contents when you use them.

Dash is designed to be small and fast so that it can run scripts faster.
It doesn't need bloating with pushd/popd.

BTW whenever I change directory in scripts, I make sure that I'm in a
subshell by using ( and ), which guarantees that I get back to the
same directory however the script finishes.

Cheers,
David.
