To protect against potential abuse, the flag D is currently required
to run commands. As #wikidata-fr is dedicated for Wikidata work, and
there is no particular issue on this channel, this access control is
more a blocker for legitimate work than useful to stop vandalism.
This change removes this access control for whitelisted channels,
and keeps it in other channels.
Fixes T903.
[ New registry setting ]
- wikidata.channels: a list of channels where everyone is allowed to use Wikidata commands.
