That presumes you've got a usable assembler for the target.  Even if you
do, you then want one in Forth, so then you have two assemblers.  Why
not just one?

I think Jones chose Forth to show bootstrapping from assembler.  Eforth
does have a metacompiler but it's quite messy and complicated compared
to the Fig approach.  Ting supposedly chose asm because he thought it
was easier for newbies to understand asm than metacompilation.  There's
a rant about that somewhere on Jeff Fox's site.  I'm not sure I
understand the portability argument about ciforth.  For example, I don't
see how I'd target it to a new chip.
