This perspective is one of the major indicators of an engineer with more experience managing real projects. Making a technology choice or transition is a milestone/roadmap affecting decision. To do so for preference over deliverability has killed many a project.

Eh, I'm pretty sure Backbone and Knockout are more stable than React :) They didn't have a release since 2019.

I mean, React itself is quite fine with backwards incompatibility. But how many completely backwards incompatible versions did react-router have? I think there four, but I can be wrong.

I can't agree more on your point made on deliverable.
