I'm -1 on this until we have an actual replacement for the Observer. I think that the observer provides significant value outside of just sandbox browsing:
1) Exporting task-level statistics. 2) Providing an easy view of a process's command-line 3) Providing a holistic view of the task config 4) Real time utilization stats As a cluster operator, I use all of these features on a daily basis (especially when I'm on call) in addition to sandbox browsing, so I don't think that these uses cases are that rare.
