Considering that Steemit is a social network whose stated objective is the creation of content, the predominance of the best quality works and the generation of profits, I would not think it would be a bad change to introduce the comments resteem. This taking into account that the comments can sometimes have the same or greater extension and quality than the post in which they were written. From my perspective, this could have two logical consequences: the first, that a person decides to fill their feed with irrelevant content, and the second, that can nurture their profile of the best content of other authors (while helping to boost that content).
