Revert views missing. Any workarounds? In Drupal 8 reverting views to their original (in the core, custom or contributed module) became difficult. Supposedly the module config_update would allow reverting a view, but that promises to be a more laborious than simply clicking a link like we were used to in Drupal 7. 

I was wondering if it would be possible to make selected views read-only? That way administrators with Views UI permission would have no edit link forcing them to work with a duplicate. 

Hints on how to accomplish this? Any other possible workarounds?
A simple workaround without an additional module would be to copy and paste the content of the yaml file views.view.[view-id].yml you find in the module's /config/optional folder to www.mysite.com/admin/config/development/configuration/single/import.

Select the configuration type "View" and add the first line containing the UUID from the active configuration (switch to Export - Single item).

If you have to do this on a regular basis then the recommend way is to manage the configuration with Git, see this tutorial Using Configuration Management and Git to Track Drupal 8 Configuration.
