What's wrong with stability, LTS, and not fixing bugs for "compatibility".

[kinke]

I fully agree, but must add that I also don't have to maintain a 
codebase where it'd matter much. ;)

What makes matters worse in this regard is the Buildkite CI 
integration. E.g., https://github.com/dlang/dmd/pull/11387 is a 
bugfix but blocked as it breaks 5 3rd-party projects. Frankly, I 
have more important stuff to do than to fix unrelated code to get 
a fix in. Another bugfix, 
https://github.com/dlang/dmd/pull/10124, broke one Buildkite 
project; I've adapted it but still had to wait for over a year 
(incl. rebasings and solving merge conflicts of course) until a 
new tag was finally available and the fix could finally be merged.

Checking the impact of PRs on 3rd-party projects is of course 
valuable, but we need to find a solution for bugfixes breaking 
some of these.
