Keeping in mind that I have little intuition of how this would actually be implemented, or even what would be desirable from either a technical or a community perspective, it seems that a reasonable angle of attack would be to allow blocking a user from exercising a given userright(s), at least for handling the "Actions" component of this functionality, otherwise it seems likely that we'll just keep ending up back here with additional desired blockable actions.

This comment is created based on a duplicate task

This feature should be extended to block or unblock editing of or doing:

• All content and talk pages
• All content pages at once
• All talk pages at once
• All pages in some namespace
• User's own pages
• Other users' pages
• All pages belonging to a specific user
• Mentioning all users
• Mentioning specific users

The commands will be executed in order of placement.
So Block A* and then Unblock AA will allow AA but not AB

Examples:

Block namespace: Talk
Unblock pages: Talk:AAA

The user can edit articles, but only editble talk page is Talk:AAA

Block namespace: Talk
Unblock pages: Talk:AA*

The user can edit articles, but talk pages must start with "AA" to be editable

Block content pages
Unblock page: Wikipedia:Village pump*
Unblock page: Help desk
Unblock page: * noticeboard

The user can't edit content but can discuss it. Useful for users on probation for further unblocking.

Thanks for adding the tag, @Ammarpad.

Thanks for your note, @Monniasza. We are hoping to do some maintenance work on this project in the near term. I will update this ticket as needed.

Here are more commands:

• Pages not belonging to a category
• Pages belonging to a category
• Pages not belonging to a category and specific sublevels
• Pages belonging to a category and specific sublevels
• Specific pages
• Page regex (most advanced filter available based only on the name)
• Mention regex
• Username regex

Here are more examples:

Block mentions of endangereduser
Block pages belonging to endagereduser

Block user pages containing regex: (jew|israel)
Block mentions containing regex: (jew|israel)
Block article content page containing regex: (jew|israel|antisemitism)

Possible block of an anti-Semitic user. User can still discuss articles, but can't mention or message users with names related to Jews.

Are partial blocks done?

For the time being. There are many outstanding requests on partial blocks and we hope we can pick up work on this again in the near future. In the meantime, there are several awesome volunteers who have been working on the project.
