My experience has been that functionality that was thought to be Unix
specific has gradually become available on other platforms, which
makes it hard to decide in which module a function should be placed.
The proper test for portability of a program is not whether it imports
certain module names, but whether it uses certain functions from those
modules (and whether it uses them in a portable fashion). As
platforms evolve, a program that was previously thought to be
non-portable might become more portable.
