That is true. However, I believe developers will spend less resources to bring the full experience to those older platforms and (common with graceful degradation) and the evergreen platforms with ES6 support will be the main development target with an increasing number of apps/sites just dropping support for those older devices altogether due to the development costs. The cost is not just setting up a webpack config, but also testing alternative builds of the code and making sure they run on the older platforms and debugging them.
