I understand how .pth files work.

The rationale for requesting the "vendor-packages" approach, is that Python files,
as supplied by the vendor (Sun, Apple, RedHat ...)  with their operating system
software, should go in a totally separate base directory, to differentiate them
from Python files installed specifically at one site.
