Sure but if you're going to go that far, that's basically like saying we shouldn't have breaking releases ever. Sometimes, tech needs to evolve in the face of other threats, like React overtaking Angular.

“Evolving” implies slowly changing to keep it modern. C# “evolved”, Java “evolved”, the C standard library and C++ STL has been “evolving” for decades. But they all maintained backwards compatibility.

Again, that does not mean backwards compatibility is good. See how bloated C++ is in an effort to keep BC while it should have long ago broken things to be a more lean language.
