@weitzman what's your opinion on this one? Seems useful to me, and the implementation very simple because we can leverage a lot of Drupal core code.

[weitzman]

I don't recall anyone ever asking for this. I'd like for a couple people to say "I have needed this" before we consider adding a new command.

[DieterHolvoet]

I just found this command already exists in the config_inspector module: https://git.drupalcode.org/project/config_inspector/-/blob/2.0.x/src/Commands/InspectorCommands.php

[weitzman]

Do you see this being used by module authors or site owners or both?

[DieterHolvoet]

I'd say module authors, site owners should rarely edit config immediately without some kind of UI. If there are issues with config schema, most of the time it will be the job of the module author to fix it.

[weitzman]

OK, lets leave this to config_inspector.
