We are thinking about the upsides and downsides of each feature a lot and would never do something that would be a waste of blockchain resources. See for example this discussion with @gtg.
First of all, this feature doesn't need to be there until infinity. When the proportion of all Steem votes going through Steeve would become too high, the information value of the comments would decrease significantly. So there would be only the financial aspect. Then we can decrease the number of comments by making let's say 1 comment per 10 user votes and give it 1 beneficiary vote for all of the 10 original votes.

But this is entirely different volume of traffic ( compared to weekly post with aggregated data to showcase best picks, etc. )
