agree with the "this is unnecessary" sentiment, just as i thought it was unnecessary to add the "less frequent rest moments are acceptable if song calls for it" as it's totally redundant and self explanatory
making such clarifications explicitly written into an RC that many mappers already consider a list of checkmarks instead of a base to build their levels upon while having clear limits will only lead to low diffs becoming almost entirely like they were mapped by an AI that uses a checkmark list (if they aren't already...)
edit: re:the last paragraph, the RC is already this flexible, the issue is entirely self-made by the mapper in their own head either of their own volition or by an unexperienced modder who considers the RC a holy literal bible instead of trying to read between the lines
