There have been a few research articles showing that in the last few years too that says the same thing. The minutes thing won't be true, for heavy weights you need to warm up and ramp up, but yeah it can cut down your gym time significantly, and if you are fatigued from lifting, this can cut down your fatigue significantly too.
I'm not sure there's a ton of point warming up. It feels good, sure, and if you are doing maximal lifts it's probably a good idea to feel out how close your are to your limit, but otherwise I don't see how warmups help.
I didn't bother most of time when I was training. I might do a couple reps a plate down, or a set with just the bar, but never did more than that.

It's been known for decades. I remember 20+ years ago pointing out to people that according to the research, multiple sets are inferior to one set (i.e. load that one set high vs a smaller load so you can do 3 sets).
I've been doing it for years with no issue. Intuitively, the idea that muscles/joints require "priming" seems really odd and not very useful from an evolutionary perspective. Cats don't warm up when they jump 5 ft.
Form is the major thing. I have to get used to the exercise, remember good form, get used to the good form, before ramping up to heavier weights. I don't want to go heavy quick and have problems if I have more fatigue on a particular day or I am not concentrating. Honestly, I have never not ramped up, so I don't even know if I could do that, but I am not about to try either lol.
I don't think "priming" your muscles is necessary because it's an evolutionary advantage, but because that's the best muscles evolution has come up with so far.
It's like saying "why would I have to change the oil in my car, why would an engineer make an engine that needs that?".
And jumping 5ft for a cat probbaly is the priming, that's not peak performance for them.
