If you care, please take time to upvote or file bugs on packages that don’t follow XDG. Or even better, make PRs.
A (very well used) program I use places files in $HOME. Someone argued for changing to $XDG_CONFIG or at least add that as an option. The dev, being used to the old school way, gave the exact opposite reason: that .config was just an extra level of organization when dotfiles are what the home dir is for. So I’m not sure how successful you would be with that approach.
To be clear, I am clearly on the side of XDG, myself.
Those bugs and PRs would just get closed without comment. Nobody is going to move a dotfile as a breaking change in any established software. You either get it right the first time or probably never.
They will if enough people whine about it.
In the old days (I’m 50+) tumbleweed drifted through ~/ apart from my drivel and I’d have a folder for that so /home/gerdesj/docs was the root of my stuff. I also had ~/tmp/ for not important stuff. I don’t have too much imagination and ~/ was pretty clean. I was aware of dot files and there were a shit load of them but I didn’t see them unless I wanted to.
This really isn’t the most important issue ever but it would be nice if apps dumped their shit in a consistently logical way. XDG is the standard.
The software can read from both locations in a backwards compatible way. Many tools already do this.
The best way to handle this is to have the next version move the old directory (if it exists) and then start reading from there.
That way it’s in compliance from then forward.
A UI notice is nice but will probably be ignored.
I’ve made about 5 MRs changing dotfile locations, and not once has it ever been declined
I don’t care.
I know developers are busy, and I don’t mean to berate them for their choices or work. I only have a two year Computer Information Systems degree and haven’t programmed a lot for a while, but supporting the XDG specification and remaining backwards compatible doesn’t seem to be very difficult or would cause so much breakage (of course, the amount of work would depend on the software and how the hardcoded path is implemented). I look up git repository issues for the software and tend to find ubiquitous examples like vim to be resistant to such change: https://github.com/vim/vim/issues/2034
This is really frustrating and leads me to find alternative software, such as neovim/doom emacs instead of vim, nushell instead of bash, etc., just to be able to clear up my home directory. I don’t mind if I have to wait for XDG to be supported, but many important projects just label the issue as “won’t fix”. I totally understand where you are coming from.

XDG is a Red Hat thing.
Stuff outside of their influence is unlikely to change, like OpenSSH or ZSH.
Old things like that get a pass. New tools and frameworks should definitely obey the standards.
