I get your point, though it's also worth pointing out that it doesn't force anything. Admittedly, syntax highlighting will generally help but it's always possible that a skim simply misses the keyword. Practically speaking, that's not how I know Ruby to be written. The convention I follow is to use `unless` when there is no `else` case and only when there is no negation in the expression.
