It's the same with every Major update with breaking changes. This is not even macOS specific, if these updates wouldn't happen, every software would be like Windows or MS Office which stays backwards compatible for decades. It makes sense to adapt as user and also that developers need to adapt, e.g. to create 64 bit software. Also there are always work-arounds.
