3 re-writes from scratch in 6 years, I know front end is dynamic but to be useful ship a code and mantain it.
Crap tool is better than unestable one.
First, it's 2 rewrites. Second, those were all 98% backwards compatible for the users (might need to upgrade plugins), and just refactored the internals.
But sure, let's all write perfect code on day 0, taking into account all the ways libraries you depend on (React) can develop in the future. It's not like "frontend" is a moving target or anything...
