Why no fluted bezel platinum Day-Date?

[Saturninus]

Maybe a question with a simple answer, but why does Rolex offer the platinum version of the Day-Date with a smooth bezel only?

The fluted bezel is the iconic look for this iconic watch, and why not offer this prestigious watch in the finest metal with its most iconic look?

I suspect it has something to do with the fact that platinum is much harder to work with than gold. But is it impossible to make a fluted bezel out of platinum? Maybe it would be impractical and expensive, but then again so it a platinum mechanical wristwatch in the first place!
