No. The Drafts extension (and any feature that puts hidden content on the servers) was veto'ed years ago by Legal. We need to stop beating this dead horse.

Err, what? Quick don't tell legal about Special:UploadStash, or the "userjs-" options api.

As a quick hack I made a little user script that can do auto-merging of edit conflicts. It adds a button to the edit conflict page to auto-merge the conflict.
To try it, add the following to [[Special:MyPage/common.js]] or [[meta:Special:Mypage/global.js]]:
importScriptURI('https://meta.wikimedia.org/w/index.php?title=User:Bawolff/EditConflictAutoMe...');
The script is extremely basic and rather "unpolished". I'd be interested to hear if even something as basic as this is useful to users. Remember if you try and test an edit conflict, you cannot conflict with yourself, so when testing edit conflicts you need to use a different user (or an anon) to conflict with you.
