Change 308764 had a related patch set uploaded (by Urbanecm):
Enable RC patrol for fiwiki and some permissions changes

Will be deployed at September 07 13:00-14:00 UTC. This might change due to my time availability.

Hmm, I think that there is still old autopromote for patroller group which should be removed at InitialiseSettings.php?

'wmgAutopromoteExtraGroups' => [

	'fiwiki' => [
		'patroller' => [ '&',
				[ APCOND_EDITCOUNT, 1000 ],
				[ APCOND_AGE, 100 * 86400 ],
		],
	],

Sorry, I understood your task wrong. I thought I shouldn't set up any kind of autopromote and not I should remove autopromoting. Fixed, see the patch.

May I suggest to stop using FlaggedRevs-like usergroup names (if FR are
removed) and name the groups autopatrolled and patroller?

@MarcoAurelio This is for me or for @Zache?

It looks fine to me and thanks for the fast response.

Just thinking out loud. Don't worry :)

@MarcoAurelio, currently we don't have in fiwiki plans to remove FR.

Ah, then I misread the request. I though you were requesting this because
you wanted to remove FlaggedRevs, which is not the case. Sorry and thank
you.

And still one suggested change. I think that the values should be key => value pairs as the other values in groupOverrides are (?)

Eg

'editor' => [ 'patrol', 'autopatrol'], // T144817
'reviewer' => [ 'patrol', 'autopatrol' ], // T144817
'autoreview' => [ 'autopatrol' ], // T144817

to

'editor' => [ 'patrol'  => true, 'autopatrol' => true], // T144817
'reviewer' => [ 'patrol' => true, 'autopatrol' => true ], // T144817
'autoreview' => [ 'autopatrol' => true ], // T144817

Oh, thanks! Going to fix it...

Fixed.

Thank you, it seems to be working as planned.

For other who are using the FlaggedRevs and planning to enable the recent changes patrol for getting the rc_patrolled flag. In finnish wikipedia we also locally hide the RCPatrol UI elements from UI with following local CSS:

.unpatrolled { display:none }
.patrollink { display:none }
.mw-enhanced-rc > .unpatrolled { 
	display: inline;  
	visibility: hidden; 
}
