Alter language select on a node add/edit form Wonder if anyone has had any experience altering the options presented to a user from the language select on a node add/edit form. I have some custom access control ont the site and basically I'm looking to remove options based on a individual editors access to approved locales. If they haven't been approved to make edits for a certain locale then they shouldn't see an option to add a translation for that locale in the dropdown.
See http://cgit.drupalcode.org/redirect/tree/src/Form/RedirectForm.php#n70

The language widget/form element is designed so that when you explicitly provide some options, then it doesn't add the default.
