I don't think it's just people seeking the easiest way out. Doing an Ironman is NOT an easy route to take, even if you finish past the cutoff!
The reality is that the IM is a lonnnnggg race. It's hard, and really hard for most folks who train less than 12 hrs/wk.
Add the substantial number of 50+ and female AGers who aren't going to naturally go as fast as a M30-35, and I really can't blame them for wanting a longer cutoff. Or even a shorter, easier swim - I embrace swimming as much as most, but when you're faced with a 112 mi bike and then a marathon, it's pretty normal to give up some swim training to make sure you can survive that long bike/run.
Right now I'm M40-45, and while I seriously doubt I'd be in danger of missing an IM cutoff at 17hrs now, ask me again in 20 years - I suspect that even if I'm just as motivated as I am now to train and race, the age alone will put me at risk.
