It’s likely beneficial to be as inclusive as possible when picking two possible changes with the same costs. Comparison between change and no change, though, should not follow the same line of thought, for changing the rules has an inherent cost over not changing.
In other words, if today we’re in a situation where “we need to restrict to something tomorrow, do we restrict to >100 or <>64?”, then <>64 is likely a reasonable choice given what we know. We are, however, in a situation where “status quo is restrict to >100, do we do nothing, or change it again to <>64?”; I’d argue that the latter has a higher bar in terms of justification.
