- remove support for passing a single value to a format string

But won't that clobber a large number of the simple
use cases that you want to keep %-formatting for?
Note the part of the proposal that allows *any* iterable on the right
hand side rather than the current insistence on a tuple. So the
single-value use cases can be boxed easily with a list.
To my mind salvaging %-formatting requires removing the ambiguity over
whether or not the right hand side will be iterated over.
But then this breaks code where iterables are intended to be output
using a single %s format specifier, for example. I don't see why this
would be regarded as helpful. To avoid breakage I'd rather keep the
%-formatting ability as it is, and label it a legacy feature, rather
than "salvaging" it. It's going to be too tricky to convert using 2to3
otherwise.
