It appears that $PWD is a shell extension, so I don't think so.
No, POSIX requires that $PWD always be accurate, so that part is portable.
Yet I tested it with a shell by doing a cd and the value produced did

it is portable. Not all shells still in use are compliant with
current POSIX specifications.
