Heads-up to the corresponding engineering team, to make sure they have capacity for handling potential followup feedback and support input.

Is there more information on this by now? In my eyes, AMC should become default as soon as possible, so having a trial like this could be very helpful.

Advanced mode is a set of features just like beta features on desktop so currently this request is "enable all the beta features!".

Any of these features can be enabled individually by a configuration change and is probably worth considering each individually if you want to run an experiment/trial

Many wikis for example have already enabled the talk tab page feature and many wikis have enabled the desktop special pages to mobile users.

Features I am aware of (but there may be more):

$wgMinervaShowCategories
$wgMinervaDonateLink
$wgMinervaTalkAtTop
$wgMinervaHistoryInPageActions
$wgMinervaAdvancedMainMenu
$wgMinervaOverflowInPageActions
$wgMinervaPersonalMenu
$wgMFUseDesktopSpecialHistoryPage
$wgMFUseDesktopSpecialWatchlistPage

Well I am assuming the ask here is to make all the features currently available in Wikinews AMC mode available for logged in users. It's a bit ambiguous but patch is very much welcome if someone feels inclined to work out what the mediawiki-config patch looks like and make the change.

Thank you very much @ovasileva and @Jdlrobson. Sorry for the delay in replying, I was on a wikibrake.
