Sorry, I don't consider this relevant.

It's nice to have this feature (which, if the setting isn't removed along with so many other recently removed settings, can be disabled by the user) on wikitext pages since you can loose hours of work.

In Wikidata you will never loose more than a few seconds of work.

If we introduce this it will be annoying for many users and most probably needs an other setting separated from the users "wpuseeditwarning" setting. I don't think this is worth the trouble.

I think this should be closed for now (or at least set to "low") and maybe reopened if the Wikidata editing interface is changed in a way you can loose more than a few seconds of work.

Do we have a rule regarding merging new tasks into old tasks?

Here I created T248859 based on a recent request from a user, and it got merged to this one, that has almost no description and contains quite outdated comments. I think it would have been more useful to keep the task with more description, or at least to copy the description to the old task. In the end, we end up with the good description being quite invisible.

It's not the first time that it happens with tasks that you merge @Bugreporter. What do you think?

@Lea_Lacroix_WMDE I think merging into the older item is usually a good idea (potentially more comments, more subscribers, more links from outside of Phabricator etc.), but the descriptions and titles should be merged/updated as necessary. By the way, I don’t consider the comments outdated—the time spent with one edit didn’t get considerably longer over the years, although some typo fixes in the label can take several hours if it’s hard to find out what the right version is, so I think it’s a useful feature for Wikidata as well.
