The counter example is if you want to print a pair:
.say for %hash.pairs.sort: { .value };
In that case it would be nice to have the key appear in the stringification.
I see no problem as long as say gets a pair as argument. Then it can
print the key and value

That's a good point. Is there an easy way to distinguish between
passing a pair into a positional parameter vs. passing a value into a
named parameter?

Same thing with stringification. In general I think that a pair should

The only use case I can think of is sorting a list of pairs;
should it default to sort by key or value?
But this isn't a case of numifying a Pair, or of stringifying it - or
of coercing it at all. If you've got a list of Pairs, you use a
sorting algorithm that's designed

Agreed.
If you've got a list that has a mixture of Pairs and non-Pairs, I
