The immediate reason why it's relevant is that it affects what `sxhash`
needs to do.  The existence of `compare-window-configurations` is not
directly relevant to the question (tho it arguably makes it less
important for `equal` to behave structurally since it provides an
alternative for those callers who would need it).
