It's also fascinating how many developers got so burnt on IE11- compatibility issues and feel a need to use Babel as a comfort blanket still. Babel does so very little now with reasonable, up-to-date Browserlist defaults (but still takes a lot of time to do so very little), but the number of developers unwilling to drop Babel from their build pipelines is still to me so surprisingly high. Babel was a great tool for what it did in the "IE11 is still an allowed browser" era, but you most probably don't really need it today.
