Can anybody shed any light on why i586 is the default tune, rather than
i686, and for that matter why there is no i686 tune?

Would there be any objections to creating an i686 tune and setting it to
default?

i586 offers the widest compatibility with less performance penalty.

I don't think it'd be a problem.
