The last one is probably true, though. Most Android users don't care about sideloading. Those who are being pressured to do so will face the 24 hour lock.
On the other hand, I'm an iPhone user who knows Android as well as anyone. So if I were to pick up, say a Pixel 11 Pro or a Galaxy S27 (so, looking at next year's lineup), the first thing I'm gonna do is hit that developer option to enable sideloading. I know where it is. I know how to unlock it. And I know the risks. In the meantime I'm gonna set up Nova Prime, I'm gonna put Poweramp on it, I'm gonna be setting up KLCK and KLWP (and maybe KWGT) and all the other apps. By the time I need to sideload anything, I'll have the important stuff out of the way and shouldn't have to wait that long.
