Eh, I don't think it's as bad as you make it sound. It's not "constantly", it's the first major migration effort for Reviewable. And honestly, I probably could've stayed with Angular 1.x for a few more years (it's still being developed, after all), I just got tired of working around its performance issues. There's also 4 years of learning how best to architect an application like this that led to the creation of a Firebase-centric model layer where Vue happened to be a good platform to build on. And even if we didn't switch platforms, a thorough refactoring would've been necessary after many years of accumulated technical debt.
