I couldn't find any consensus on this on meta for a while, and this seems to be particularly helpful when answering decision-problems. Should swapping truthy and falsy be allowed by default, when answering such challenges, unless overridden?

For example, when testing primality, one could output a falsy value for primes and a truthy value for non-primes. Is this allowed by default?
