I don't understand only one thing, why do people need new functions?
You can anticipate the change today, and write functions that do
exactly what you need no matter which way (current or proposed) python
implements:

def ensurenew(path):
    a,b = os.path.splitext(path)
    if a == '': # also possibly check if a contains dots only
        return b,a
    return a,b

def ensureold(path):
    a,b = os.path.splitext(path)
    if b == '' and a.startswith('.'): # also possibly check if a
starts with multiple dots
        return b,a
    return a,b
