Okay, I tried writing a patch as it is. I took care that hidden filters' comments and patterns are not replicated. Otherwise, nothing potentially privacy disturbing came to my mind. I'm happy to hear your feedback (and have the table back^^)

Now I'm on phabricator as well (had forgotten to associate it with the ldap account).
I'll be willing to have a try at writing a patch since I really do need the table for a research project.
