Why?
Because you either introduce a dependency on ROMCC or you need additional assembler code. mmxstack/xmmstack+GCC is not an option here because a microcode update may be required before using floating point stuff.
If I had stood up a year ago and said "Let's introduce a ROMCC dependency for all CAR boards", we would have seen a major flamewar. If I had proposed to rewrite our CMOS code in assembler, the response would not have been enthusiastic either.
