Hello all! Just to clear up the confusion here. Components built with stencil are, after compiling, just custom elements. Custom elements (the V1 of the spec) are supported in Chrome and Safari natively. According to https://www.w3counter.com/globalstats.php that means about 77.6% of users globally are running a browser that supports custom elements natively. For these browsers stencil will not load the custom elements polyfill. For IE 11, Edge and Firefox we load a 5KB gzipped custom elements polyfill automatically for you. Its also worth mentioning that Firefox and Edge are both working on custom elements, so eventually these browsers will not need the polyfill either.
