addshore:

Whitelist wildcard support added in https://phabricator.wikimedia.org/T196858
Apparently https://phabricator.wikimedia.org/T226603 is also needed

This would allow federating between all of the *.opencura wikibases?
Though not custom domains? :/

For that a different solution would be needed where the whitelist could be dynamically grabbed?
