From what I read, I thought the problem occurred only when a response to
a s/key prompt was received, is that correct?

If so, surely that can only happen on systems where s/key is actually used,
regardless of whether or not the openssh code installed had the potential to
use it or not.

If that's all correct, then at the worst this moves the problem from being
a remote exploit to a local one for most sites, as someone would have to
enable s/key first, locally, before being able to attack.
