Things like this are to be expected if you truly value "never break anyone, ever, even if everyone unanimously agrees something is bad" as an immutable goal of your software. Programming languages are especially important for this sort of philosophy... If you make a mistake and people rely on it, your mistake is now part of the way the language works, always and forever.

My hot take: Software that doesn't take this approach isn't truly serious in the same way as software that does. Personally I'm glad for this level of discipline because at some point, there has to be a "bottom"... software that we have to rely on in order to make our own code work. Not everything gets to enforce deprecation/removal cycles, sometimes it just has to Always, Always Work.
