Why aren't new wood windows made from mahogany or other hard woods?

These woods may be an option, and will tend to be denser and of higher quality than plantation-growth southern yellow pine, for example -- However, these high-grade hardwood products can be very expensive. Also, if window replacement is being considered for sustainable reasons, it is far greener to retain and repair an existing window than to have timber shipped thousands of miles to be manufactured into a new product. let's not get into global warming and carbon foot prints - OK?
