This project also involves a ton of custom WMCS support: a private staff-manager postgres database, an nfs server (T300694), and a bespoke proxy layer (T233995). I don't love the idea of killing off a long-useful project but I won't mind ripping out all that custom infra.
@dschwen, as far as I know you are the only volunteer who has been active in this project in the last year or so. Please speak up if you would like to defend this project. (also cc @TheDJ but I get the impression you've had enough of this)
