fast hiking : real thing or just a gear selling scam ?

A while ago on the American gear testing blog outdoorgearlab, you could see for some of their gear review that it could be used for "fast hiking". And now gear brands are launching a whole new geartype just for "fast hiking". According to this video by Millet : https://www.youtube.com/watch?v=GQTCNgBIb8w it's basically clocking the best time on a given hike with breathable gear, hiking poles and low shoes, similar to trail running shoes, but you're not supposed to run. I've seen it now mentioned on some French websites.
I honestly don't see the point and think it's rubbish, or borderline dangerous. It seems to come from the US, but if you've been to Yosemite or any mountainous national park in the US, you know their walking tracks are in very good condition, and are very wide. Have you ever seen it in Australia or NZ ? I haven't, and I haven't in Europe either. To me it's a dangerous practice if done in Europeans mountains : our tracks are in poor nick, often really narrow, vertiginous, or unstable like in boulder fields. A group of fast hikers there would erode the track more quickly that regular hikers, and on steep boulder fields and moraine, there's a chance of rock falling on other walkers below them. But Millet, Merrell, Salomon, La Sportiva and others jumped on the occasion, launching "fast hiking shoes", or new breathable jackets and shirts... I wonder what's next : fast snowshoeing ? Maybe dozens of deaths by skiing-triggered-avalanches in the Alps each year isn't enough...
My thought on it is that's it's been basically made up by gear brands and that it has no base in reality. I've never seen a fast hiker like on Millet's youtube video, never heard of people joining a "fast hiking club" or anything like that. And if you google it, you'll barely find anything else than gear webshops. Have you guys ever encountered fast hiking enthusiasts ?
