No - Polymer is not a web standard - Web components are (https://www.webcomponents.org/specs https://www.webcomponents.org/specs) - and are implemented as a standard (its not fragmented all vendors agreed on v1.0, chrome, safari, opera already ship with them, MS and FX are close to follow) - polymer is just 30kb on top of that to make your life easier. This is exactly what you described with asm.js. It just happens that out of all libraries that help you create web components, polymer is probably most widely used - well, angular 2.x can technically output web components too, but I don't want to compare a framework with library. But you can mix those components with other solutions (like x-tags, skatejs, bosonic, "pure components" etc.), they are interoperable, I even have them cooperate with legacy jquery application.
