Sure, or even if we'd encourage people to do so...

I wouldn't hope so...

I don't follow you on this comment and perhaps I'm unclear about what
I mean. I mean that I would like to have a "three" stage build of the
binutils sources. A first build with the already installed "binutils",
a preliminary build with the first stage built binutils, a "final"
build to check wether there are binary differences in the built files
(*.o mainly...) Such an approach would level some problems at the cost
of some build time.
And, as always, I'm a great guy (humble, right?) in having ideas, I am
not that great in implementing them and suggesting patches... So, I'm
not pushing this, just advocating a little...
Cheers,
