I don't like it.  The current calling semantics are sufficient for the
vast majority of cases.  For those cases that are not covered by the
current calling semantics, there is a PEP for allowing variations in
optional arguments, keyword arguments, etc.  I can't remember the number,
but the PEP index has it.

As for signaling "use the default", there is a standard method: omit the
argument.  If you want the argument to always be required to be a
keyword argument, you can use...

    def foo(arg1, **kwargs):
        arg2 = kwargs.get('arg2', 1.2325)
        arg3 = kwargs.get('arg3', 'hello')
        ...
