[META] Front-end Kanban issue tracker

This sounds like a great list
There is prior art for a lot of it in decoupled lb
I think it is worth splitting into separate issues so that people can pick up discrete tasks without duplicating effort

@larowlan Do you mean making each of those <li>s smaller, or do you mean converting them to actual issues?

Sorry I meant converting them to actual issues

Adding the child issues to the issue summary to make this easier to read.

Added following issues to the roadmap:

1. #3456084: Add initial implementation of primary menu
2. #3457634: [later phase] Add support for UI translations
3. #3454173: Media Library integration (includes introducing a new main content renderer/`_wrapper_format`)

We've failed to keep this meta up-to-date.

We're understaffed on the coordination side and have hence been unable to convey the "next steps" fully tracked in this issue. In practice, this has turned out to be impossible, because there's neither comprehensive designs nor comprehensive technical implementation plans: we've been at best been able to plan a few weeks ahead, and we've constantly had to readjust.
That's why along the way, we've been using #3454094: Milestone 0.1.0: Experience Builder Demo to keep the team laser-focused on the next highest priority per Product Lead @lauriii, who's been keeping that list up-to-date 😊

That's what's been informing what blockers to tackle to keep working towards reducing that list to zero.

Hopefully we'll eventually be able to plan further ahead.

These have not been used in ages. See #3515932: Milestone 1.0.0-beta1: Enable creation of non-throwaway sites.
