I have no intention because in-kernel FPU emulation _is_ required to
run R2000/R3000.  Even with FPA-equipped R2000/R3000, FP insn emulation
have to be done because, some of FP insns _might_ emit NOTIMPLEMENTED
exception and/or post interrupt signal line.  That's the exact reason why
NetBSD/mips has FP insn emulation code inside.  (The original MIPS code
was made for R2000/R3000, not for R3000A, nor IDT R3041).

If the MIPS phylosophy was well regarded,

you can understand above two disturbed NetBSD/mips integrity, say,
"don't touch CP1" was just an extreme case of FPA emulation.

So, I'm writing codes don't require NOFPU/SOFTFLOAT for kernel
configuration.
