>>when pypy devs tried getting python versions not relying on cpython tricks (which didn't bench well for pypy)<< NOT TRUE. Programs optimized for PyPy were accepted and shown alongside programs written for CPython. Joe LaFata contributed excellent PyPy pi-digits, spectral-norm, mandelbrot programs and they were all accepted. >>banning multiple implementations<< NOT TRUE. Measurements for both JRuby and CRuby are shown. Like everyone else, I'm sitting on my hands waiting for someone else to make and publish all the other program measurements. The implementation pick ranges from the standards that everyone uses to the experimental that nobody but the language developer uses.
