To you it is, plenty of people -including myself- don’t find it so. And considering the ratio of MacOS+Windows desktop users to those of ‘nix (an increasing number of which are new converts), middle clickers are a minority here.
But hey! At least they are only flipping defaults, not removing the feature outright, like they did type-ahead search. [Insert angry rant here]
That is gnome's standard play: move a feature to a preference (“you can just turn it back on”), remove the preference from the control panel (“you can still turn it back on using ‹whatever conf backend they're using this year›”), and then finally remove the feature (“you could only turn it on by using an unsupported mechanism, and ‹conf backend they used last year› is deprecated anyway”).
I agree with the point about this being configurable.
About your first point, however, keep in mind that "middle click insert" has been the default behavior in X since the 1980s, long before Windows or current generation MacOS's were around. To me, this is such a basic functionality, I would compare it something as fundamental as CTRL-X/C/V for cut/copy/paste on Windows.
As a trackpoint user, I am glad it's off by default.
Because of scrolling on Thinkpad keyboards (using the middle click), I had to turn that feature of every time, especially while working on longer documents I would otherwise accidentally paste stuff at random places.
From where I sit I have 5 Thinkpads set up within reach, and I have a few more in other rooms. They are by far my preferred laptop.
Most run Ubuntu as their default OS, most have the trackpad disabled because I usually use the trackpoint for everything, and on all of them I use middle-click to paste extensively.
I'm guessing you have touchpad corners enabled. Usually by default lower-right is 2nd mouse button and upper-right is 3rd mouse button (middle click).
I only use the touchpad, but knowing where it is I can avoid it and almost never trigger it accidentally. It can also be disabled without affecting two-finger and three-finger tap, which I do use.

Or in anything that's not X?
Speaking personally for me only, I don't think it's a great thing. The <however many> clipboards on Linux is... not really a great thing. I for one never know which of the buffers contain what. And this is compounded by the fact that selection may or may not overwrite what's in one of the buffers, and middle click may or may not paste whatever was in that buffer. Additionally compounded by how inconsistent the behavior is across apps.
I, for one, use the different clipboards concurrently all the time, with "highlight & middle-click" probably being the one I use most often. It's the most convenient for me most of the time:
- only two interactions (one drag & one click)
- completely mouse-based (no keyboard interaction necessary)
I was never a fan of it. I always turned it off. And now it also freed up middle click for auto scrolling which is actually great, especially when the scrollwheel is somewhat broken.
As someone that habitually highlights what they are reading it was generally beyond useless for me. It was actively making me mad when I accidenatally pasted some non-sense because I just highlighted a paragraph before and accidentally inserted it into something.
It doesn't. X was the only place I know of where that was a thing.
