Aline left the company in 2023 if I'm not mistaken, and as far as I know nobody has worked on this feature since. To be honest with you, it will probably remain on hold for the foreseeable future; we have too few people in the team and too many higher-priority tasks to work on this at the moment. (The patch you've seen by Page is a relatively simple UI improvement which isn't related to the screen sharing functionality.)
Ok - Thanks for the information and your answer - I think it would be currently more important that this issue will be fixed when it comes to sharing a screen: #1242 (comment 48180) (same issue since year(s)?)
