What if we can override the inner call to os.open()?
For example, io.open() could grow an additional argument "fd_opener" which defaults to the equivalent of os.open.

Then creation mode can be expressed like this:
    open(filename, 'w',
         fd_opener=lambda path, mode: os.open(path, mode|os.O_CREAT)
Another use case with openat (see #12797):
    open(filename,
         fd_opener=lambda path, mode: os.openat(fd, path, mode)
