Hello,
In the recent past (c2ce6a1b6085cf0cbf0fc2c3542fd36096bf2948), purge confirmation have been enabled on all wikis for understandable reasons.
Instead of making it a fixed function, I would like to suggest that this be turned into an option instead - i.e. the ability to turn off the confirmation (probably via LocalSettings.php). This would be more helpful for private MediaWiki-powered wikis (i.e. non-Wikimedia wikis), as the confirmation is not necessary.
Edit: Not directly related, but it is also useful (for private wikis) if a third option is available to always purge every page upon load.
I'm posting this feature request as suggested here.
This is my first feature request/suggestion. Hope this helps.
Thanks,
Rehman
