Current behaviour:
Context: I'm working on a web component library.

Stencil allow the inclusion of globalStyles in the stencil.config.ts, which then is included in the dist after compilation. While this stylesheet is useful, a very common need in component libraries would be to be able to set some rules globally for all components (think fonts, reset.css, box-sizing: border-box, etc.).

Right now, the way to do it would be either to:

• manually include the global stylesheet in all components of the library, which means that all components will now include the stylesheet itself which in turn can cause a very quick augmentation of the bundle size.
• manually configure a Constructable Stylesheet system, in order to make all your components adopt the stylesheet.

The second option seems better, and I feel that Stencil could handle this at build time instead of letting the developers implement a custom solution 😄
