~27 calendar years of anecdotal evidence across a multitude of CPython API behaviours (as well as API usage in other projects). Other implementation developers don't say "CPython's runtime behaviour is the real Python specification" for the fun of it - they say it because "my code works on CPython, but it does the wrong thing on your interpreter, so I'm going to stick with CPython" is a real barrier to end user adoption, no matter what the language specification says. Blaming users for not writing portable code doesn't achieve anything in that scenario - it just puts an extra road block in the way of those users trying out the alternative interpreter implementation.
