[META] Plan for version 2.x

> About components: We need to find a process to deal with components that are distributed across multiple origin repositories.

Some initial thoughts

The pattern approach is defining atoms, molecules, organisms, templates and pages.

Bootstrap is defining layout, content, components and utilities https://getbootstrap.com/docs/4.4/getting-started/introduction/.

Bootstrap content is mostly atoms from my perspective. Bootstrap components are molecules and some atoms (for example button is an atom for me).

Bootstrap layout and utilities are similar i would say. We do not use layout by default in a base theme and we use some utilities, we let child theme define layout rules as they like and load additional utilities as needed. I don't see any problem with this approach currently and would keep this if others are not objecting, and try to keep minimal utility loading as much as possible.

It makes sense to me we always load all atoms and molecules styles by default.

Organisms are stuff like header, footer, nodes, etc. We should probably define libraries for styles/behaviours and load these libraries in respective organism templates.

In this way, shop card and shop product page styles would be loaded only if/when they are needed.

Thoughts?

Added 2.x branch so we can group issues more easily.
