I'm not, because it breaks importing from the interactive prompt if
you change directory after starting the session.

The existing workaround for applications is pretty trivial:

  # Somewhere in your initialisation code
  for i, entry in enumerate(sys.path):
      sys.path[i] = os.path.abspath(i)

The fix for the import system is similarly trivial: call
os.path.abspath when calculating __file__ (just as runpy now does and
the import emulation in pkgutil always has).
