What is your view on maturity of web components and the frameworks used to develop web components? Like polymer etc.

Do you think it is production ready? Develop once and use it across any platform/tech stack is it really true? Can a web component work without any bridging library with any front-end framework say Angular, React, Vue etc and also with other tech stacks like asp.net , Java (where the UI frameworks used are different like JSP, razor html engine and also some does server side rendering).

Also, what is the future for web components?
