Has anyone ever written a non-twos-complement C++ compiler for this machine?
Has anyone ever written *any* non-twos-complement C++ implementation?
And... does anyone intend to write a non-twos-complement *C++17*implementation?

If the answer to these questions is "don't know", how do we find out?
Strawman suggestion: remove non-twos-complement support from the standard
and wait to see if anyone complains (with the intent that we would restore
such support if there are actual complaints, not just hypothetical ones).
The world would have nearly four years to notice and react. Thoughts?
