At the risk of asking one of those newbie questions, why bother with StrideTo and StrideThrough? Isn't a Generator or Array more to the point?

It's called StrideTo or StrideThrough, conforms to Sequence (with a FIXME comment that it should conform to Collection) and is distinct from Range and from the Strideable bounds themselves. Is that different from what you're describing?
