I assume you mean that we don't need a decimal type with a fixed number of
decimals. There is an extension to the propsed standard that allows fixed
number of decimals so there seem to be some who need it.

I know that I need fixed number of decimals in the software I am working with
and that I often both have objects with round_to_nearest and round_toward_zero
in the same application.

If I had a decimal floating point type available I could probably have used
it. It would make some things easier and other things more difficult.

Why do you mention "normalized decimal arithmetic"? Isn't that a way store
floating point numbers or do you mean something else.
