pushd/popd are intended for interactive use, not for use in scripts. It prints the full stack on directories and there is no option to be quiet. Of course, there is always redirecting to /dev/null but it is intentional to not have option to be quiet.

Usually there is no need to return to original directory. Change of directory is process-local (script-local) so the calling process is not affected by this 'cd' in the script.

'pushd' would imply that you want to 'popd' back out of it, but that's unnecessary, as the 'cd' will only affect a subshell that gets terminated at the end of the script. So for the user it makes no difference, the current directory stays the same. For the script it saves you an unnecessary 'popd'.
