This does not seem to be possible for now as far as I can see. None of the variables governing the autoconfirmation of accounts distinguish edits between namespaces. [[ https://www.mediawiki.org/wiki/Manual:$wgAutoConfirmCount | $wgAutoConfirmCount ]] just counts the edits of the account without differentiating between namespaces and [[ https://www.mediawiki.org/wiki/Manual:$wgAutoConfirmAge | $wgAutoConfirmAge ]] counts the time. Together they manage the autoconfirmation of accounts on Wikimedia Wikis. So to do this we should, I think, modify the way $wgAutoConfirmCount works or add a new configuration. Another option might be (not sure) removing arwiki from the defaults and use [[ https://www.mediawiki.org/wiki/Manual:$wgAutopromote | $wgAutopromote ]] but as far as I know this does not work for implicit user groups (such as autoconfirmed).

How we can see the autoconfirmed users on ar.wiki (or their number)? I try here but no result.

That is a list for explicit user groups. Autoconfirmed is an implicit user group. According to https://www.mediawiki.org/wiki/Manual:User_groups_table they cannot be queried via database :-( Not sure who can provide you with such a list though.

Aha @MarcoAurelio Thanks, I think we can queried it as extendedconfirmed group!

arwiki do not have any extendedconfirmed user group:

MariaDB [arwiki_p]> select distinct ug_group from user_groups;

Extended confirmed is something else. It is explicit group that is added automatically by autopromoting feature. It does not match the autoconfirmed group (and, as Marco noted, it isn't enabled for arwiki).

You must query for the info that defines when you can pass isNewbie function (it's the two config variables). See the example below.

So, in arwiki, roughly 7800 users out of 1483416 are autoconfirmed.

Can we added it to arwiki Special:Statistics? or it'll be hard?

I don't know. You can fill a separate task if you want.

You can use https://quarry.wmflabs.org/ if you need a web interface to run queries.

I meant...to fill it as a feature request, not site request. Amended.
