I can’t say about Python, but I am pretty sure react is being “configured” explicitly because the state of the frontend ecosystem is such a mess compared to other areas.

(Which, in my opinion has two reasons: 1. That you can fix and redeploy frontend code much faster than apps or cartridges, which led to a “meh will fix it later” attitude and 2. That JavaScript didn’t have a proper module system from the start)
