I considered that, too. But I don't know if everyone has that.
OpenBSD has it implemented but it's intenionally not documented.
The pwd source says:
  "The POSIX 1003.2B/D9 document has an optional -P flag"
Note the word "optional".

I guess the python libraries really are more reliable in this case.
