Not exactly: when it comes to parsing, shells on POSIX systems don’t always follow the POSIX rules.  The non-POSIX/POSIX modes in shlex mimic that.

In #9723, it was agreed to move the undocumented pipes.quote function into the shlex module.  I think we could move list2commandline from subprocess into shlex too (that’s probably another report, but I’m saying it here because Philip mentioned it), and also provide a Windows-compliant split function in shlex.
