We need to accept failure and remove this technical debt from Commons. It's barely used and we've been advising GLAM partners to not use it at all. See also the big alert at https://commons.wikimedia.org/wiki/Commons:GLAMwiki_Toolset
The current status of the tool:
- Never got past initial prototype
- Full of unresolved bugs
- No team at the WMF that has active ownership
Normally I would like to have some form of replacement before removing something. In this case we have Pattypan.
Note: I was on the steering group for the development so I'm killing my own baby here.
