establish 2021 roadmap
We should make a roadmap for 2021. This could be either milestones in GitLab, or a roadmap page in the wiki, something like:
or the original, non-trac roadmap from the wiki:
It's unclear to me how we'll make a roadmap for next year. Month-per-month long-term planning did not seem to work, or at least we definitely stopped tracking that after summer (although that could be due to the GitLab migration). I still think it would be wise to setup larger goals in the roadmap and not get tangled up in smaller details.
We should use the survey data (#40106 (closed)) to prioritize the work.
I hope to complete this in January, with the rest of the team of course (but I volunteer to bottomline this).
