No.

That's a road toward irrelevance.

Tramp has been with us for ~20 years, and ~10 years a part of Emacs. It 
has a significant number of users.

Anyway, that Tramp fix was a happy side-effect. Now that I think back, 
the main reason was the switch to the new interface which removed the 
default binding for tags-loop-continue (now called fileloop-continue).

Which made using dired-do-search a little less convenient, and people 
asked for analogous commands which used the xref UI. The original 
commands are still with us, though.

I'm sorry for the inconvenience, really. But not being able to break 
anything, even, is an ever-growing cost on keeping Emacs relevant toward 
contemporary expectations, or otherwise making it better.

But you still upgrade to the new version? Expecting something new from 
it, right?

And then Emacs users get older, change jobs, or entirely leave the 
profession. If Emacs stays as it was 30 years ago, it will appeal only 
to users who started with it 30+ years ago. And many of those have 
already left.

Emacs users are an admirably faithful bunch, but there are forces of 
nature we have to contend with as well.
