I am (well, have done - I've reviewed all the existing soft-fp code
multiple times).

I think the actual lack is more to do with limited interest in this code,
given that on the most widely used platforms it's not used for standard
floating-point types. (In the GCC context, it seems to be the Fortran
community that's most interested in __float128.)
