The importance of a comment should not have any impact in the rework that is done. Starting point is that all comments will be handled seriously and rework will be done in case the comment is accepted.
If the author does not agree with the Importance marked by the reviewer, it’s suggested that the author contacts the reviewer to discuss this. There can be various reasons for this difference in insight. One of these can be that the author does not fully understand the value the document has for the reviewer. This is a good moment to straighten that out!
In all cases: do not argue too much about the importance. It’s the product quality that counts!
