The first Asset Browser milestone should be merged for 2.92.
See #asset_browser and #asset_browser_milestone_1.
Not all of the open tasks may be done in time for bcon3 though. If that is the case, we could either keep it disabled as experimental feature until 2.93, or clearly communicate it as not feature-complete. If we want to do the latter, the coming implementation sprints should focus on stability over feature-completeness.
