You must be right.

ScaledDecimal are just fractions wrapper with special methods to read 
and print...

...that do not necessarily match your required monetary format (thousand 
separator, localized decimal point, no awfull s2 like in 5.30s2, append 
or prepend monetary symbol etc...).

So you inevitably end up with a monetary object having its own 
read/print methods, and ScaledDecimal is not of much help then...

If your Fraction optimisations are significative, please share on Mantis 
or something.
