@ppelberg Initial findings indicate that of the talk page contributors that have explicitly adjusted the DiscussionTools Beta Preference since deployed, 51% of these contributors are Junior Contributors (defined as making under cumulative 100 edits). See summary below.

Result summary:

• There are a total of 290,842 users (not limited to just contributors) that have explicitly adjusted the discussion tools beta feature across all wikis.
• Of all talk page contributors[1], around 17.6% of these contributors have explicitly adjusted the DiscussionTools Beta Preference. Here is the breakdown of those contributors by experience level

Talk Page Contributors[1] that have explicitly adjusted the DiscussionTools Beta Preference

Data Details and Caveats:

• Data on the state of the Discussion Tools Beta preferences obtained via:

Data via:

query='''
SELECT COUNT(*) 
FROM user_properties 
WHERE up_property="discussiontools-betaenable"
'''

• Assumes that the discussiontools-betaenable property has no default value, so if it's present at all the user has manually toggled it.
• I joined the user_properties data with edit history logged in the latest snapshot of mediawiki_history to determine the proportion of these users that are senior and junior contributors. For this analysis I specifically, looked at non-bot editor of talk pages.

Timeframe: we are interested in people who have adjusted the state of the Discussion tools beta feature at any point after 18 February 2021 (the date the New Discussion Tool was first introduced

The user_properties table only provides a current snapshot of the state of non-default user preferences and we do not have data in this table on the specific time the preference was changed or updated.
