What a weird question. I have no use compelling use-case for python2. I have plenty of use-cases for X, such as the fact that none of my software other than my browser has Wayland support, including my window manager.
Nothing weird about it, it makes perfect sense with what you are posting. I find it weird that you react like that to a simple question. Just probing what kind of old software you use, cause it tells a lot depending.
It was weird because you implied (and still are) that it'd mean I was hanging on to old, superceded software that has adequate replacements. I'm not. So this is telling us more about your assumptions.
I'm using my own terminal, wm, and file manager. They use X11, and I have no interest in changing that, because I have no need to as long as X11 works on my hardware and that won't change anytime soon. Everything I don't do in a terminal, I do in a browser.
EDIT: To add some more context for why I have no interest in changing that:
1) my wm is 1568 lines of code at the moment. If anything, that is more than I'm happy with. With Wayland I'd need to write my own compositor. Way too much work even with reusing e.g. wlroots.
2) My file manager is more of a basic desktop launcher. That is fine, and intentional. I may add some features to it. But the reason I'm using that rather than any of the over a dozen options I've tested is that most of them either never had or have ripped out spatial features, and the ones that had some spatial features didn't act the way I wanted them to. I want Amiga-like semi-spatial features of being able to selectively snapshot icon and window placement ("semi-"spatial because traditional spatial would imply a single instance of a window for a given path; I just want default placement to be the same as last time I snapshotted it). Wayland on purpose refuses to allow that, and so I'd need to hack on a compositor or write my own to be able to support the most important feature to me in the file manager.
I'm not going to tolerate my usability being reduced just to switch away from software that does what I want it to, to software that offers me nothing new that I want and takes away features I do want.
I'm curious, what were you hoping to learn about their use of python 2? If you had specific questions, it would be helpful if you ask those, instead of trying to ask through euphemisms.
If it was maintained (security fixes and platform support only), but with no other changes, it would be a very tempting alternative to python3 for the many times API stability is valuable.
