The rolling start will thin out the pack. You won't have 2500+ people all starting at the same time. They will spread those people out over 20 minutes. It will be easier for safety personnel on the water to identify people in trouble more quickly. Also, with less of a concentration of athletes on the course safety personnel will be able to get to those athletes in distress quicker. Some people might place themselves in a start time that is far above their ability level in the swim and they will have to deal with the consequences of their decisions along with the safety assets on the course, but again with less concentration of athletes on the course at any one time it will make it safer and easier to manage for everyone. But again, this is from my perspective.
If you have less of a concentration of athletes going into the water and where they are spread out over 20 minutes (which is more than a few minutes), you will have less of a concentration of athletes coming out of the water and then onto the bike course. Fairly simple course management.
I don't know exactly how they will manage the 17 hour cutoff, but I would guess that the people that self-seed towards the front (faster triathletes) and would be getting an extra 20 minutes on the 17 hours cutoff, don't need 17 hours to finish. The people that are slower and self seed towards back will get 17 hours to finish. And, in my experience, at IMTX there are typically less than 20 people at end of the race that don't make the 17 hour cutoff.
So... basically rolling starts are safer by concentrating on the back end of the field. But shouldn't the kayaks / boats be doing that anyways? At least with mass starts the safety crew can track with the backmarkers and be within a reasonable distance of anyone else who may run into trouble (and we've all heard of competent OW swimmers who have unforeseen problems, haven't we?)
Also, it does sound like you're leaving the overly ambitious self seeders to their fate.
I understand your point on the bike section, but stick by my comment that it's giving a disadvantage to the mediocre swimmer / stronger biker skill set. Likewise, you're left alone to race your race on the run, rather than knowing your competitors and how much time you've got on them/ they've got on you, and psychological aspect of that.
It does sound like they're changing the format to accommodate more starters than would be safe, and pandering to those who haven't / couldn't / wouldn't put in the relevant practice to have a degree of comfort in OW.
I've heard a number of arguments why rolling starts are good (IMUK is doing the same this year), but I'm still not convinced that it's not simply to dilute the experience for the benefit of those that arguable shouldn't be on the startline in the first place, and inflating numbers for greater profit. I'm looking forward to further comments on the subject though.
