That's not my experience.
Of course the removal of 32-bit support in macOS Catalina was a killer, but otherwise I regularly use a number of older apps.
Here's a notable example: via Rosetta, I'm still using the preference pane RCDefaultApp 2.1, which was last updated in 2009. It still works 14 years later! https://rubicode.com/Software/RCDefaultApp/index.html#versio...
