I am planning to remove the main namespace from the wgExtraSignatureNamespaces configuration setting on this wiki. I think this will have very little impact, but letting you know just in case. For more context, see task T291630 (although I'm happy to reply here if you have any questions).
Currently, that configuration setting affects:
- Whether there is a "Signature and timestamp"
button on the editing toolbar in that namespace - Whether DiscussionTools's reply tool and new topic tool are available in that namespace
It was configured that way in 2014 for all "special" wikis (basically, anything other than the Wikimedia projects with multiple language versions), on the assumption that they often have discussions, including their "village pump" equivalent, in [main namespace]. This doesn't seem correct for this wiki. We're planning to use that config setting for future discussion-related features, and it would probably be unexpected if they showed up in the main namespace here.
Please let me know if there's any problem with this. Thanks.
