This fits very nicely with the rough 'when to be compatible'
guidelines I've been using.  If we can import a function from XL
directly then the routine needs to be as compatible is reasonable
(eg matching strange date math, but not matching precision).  As
soon as the function has a different name, or an extra argument
we are free to make things rational.
