It's usually the result of deprecations that have warnings for several releases before being turned into errors. But there have been a few more deprecations lately than previously. In at least one case (disabling "alias this" for classes), I think Walter expressed some sympathy since there isn't always something obvious to do instead.

I have D code I wrote back in 2008 that still works fine today.

That said, there are often small breakages scattered around and it can be annoying. If it is your own code, you spend the 5-10 minutes to update it (with some exceptions, the last couple months have been particularly bad, most aren't like that though). But if it is someone else's code and you have to wait for them to update it then push a new version tag, and cascade through the dependency list, that can suck.

of course dependencies suck so you get what you pay for lol

You pick a version of the compiler and stick with it until you're ready to try a newer version?

It's absurd because it's not really true.
