Not so strange, as they were never intended to be used for compilers to begin with (you'd write assembler code by hand). The basic idea with having 80-bit internal precision is that you could load your 64-bit values from RAM, compute on them with so much extra precision you could basically ignore precision issues within your expressions, and then store the result back correctly rounded.
