I'm sure we're only a few years out from having a half dozen guys all have a quad axel in their arsenal
We are not a few years out from six guys all having a quad-axel. This will not be the case for a number of reasons. Not everyone is going to have the ability to master a quad-axel. It's still difficult enough for many male skaters to consistently land technically sound 3-axels.
Plus, the men's field, especially top and up-and-coming phenoms, are still trying to master four revolutions on all the basic jumps, while ensuring sound technique on their 3-axels.
The axel is considered the most difficult jump in figure skating. It does not come easily for everyone. The men who are flirting with training quad-axels are most likely guys who have excellent 3-axels.
It's going to be important to see how Ilia does with smoothly incorporating the quad-axel in his competitive performances, as well as in his training (both regular training and injury preventive training). I don't think he'll be throwing quad axels around liberally in his programs. He's gotta be strategic and pace himself, as well as spend time on improving other aspects of his skating.
After Dick Button landed the first triple jump (the loop) in competition in 1952, it took about 35+ years before quad jumps started being successfully landed, and then another 15 to 20 years b/f quads became better established. And even then, officials botched the process of figuring out how to value quads in the scoring system.
More directly relevant to Button landing the first ever triple, it took around 30+ years after 1952 before triples on all the jumps were widely mastered and incorporated into the skating disciplines. BTW, Button also landed the first double axel in
1948. The first male skater to land a successful 3-axel in competition was Vern Taylor, of Canada, in
1978. How many fans know that? I had to look it up. Of course, everybody knows Dick Button, but that's largely because he became a familiar face in fs broadcasting and event creation and production. Plus, Button contributed so much to the sport. He invented the flying camel spin, which used to be called the Button camel. We should all know a lot more about all of the wonderful pioneers of figure skating. I make time to read Ryan Stevens' Skateguard blog. He's a skating historian, and a former Canadian competitor.
My point is that in talking about quints, it's important first to understand the trajectory of jump development. If we don't connect our enthusiasm over jumping advancements with the actual trajectory of jump development in the sport, then we're not speaking from fact-based knowledge. Without being interested in the sport's history, or looking into what boot manufacturers are doing to help lessen the harsh impacts on skaters' joints, etc., then we are just shooting the breeze, without making a lot of sense. That's fine too. But I think it's more helpful to the growth of the sport, and to my own enjoyment to try and bring a greater understanding of what the sport is about to my fandom-based discussions.
