Pedals truly is a 10 min job, and the 8mm bolt standard isn't going anywhere anytime soon; even with 12sp or whatnot around the corner. Campy, SRAM, Shimano, BB standards, 1x, 2x, 3x... these things can come and go, but the pedals will always fit and work.
I changed the BB out on my gravel bike so that I could have 24mm cranks on both bikes. I don't swap in the PM too often and I'm not the speediest of wrenches, but it's still a job that's too brief to warrant cracking a beer. And I don't need much of an excuse to crack a beer (see waistline).
