user and group of results directory (specified by --output_folder) are both root

This does not break anything, but does complicate my mediocre workflow where I save results in a folder synced via Dropbox. So it is a matter of convenience.

I do this because viewing results, sharing them with collaborators / advisors, formatting figures into manuscripts, etc. is easier on macOS than a Linux terminal with no GUI.

I presume the team has an efficient way of viewing results and moving them from GCP to emails, Keynote slides, etc. Would be good to hear how it is done now.
