In the API documentation for node_permissions_get_configured_types() it says:
To exclude a specific node from getting permissions defined for it, set the
node_permissions_$typevariable to 0.
This is correct for Drupal 7, but not correct for Backdrop. From looking at the code, it is referring to the setting "
$info->settings['node_permissions']" which would be specified in the node definition originally passed to
I think this also should be documented in a change record.
What's my next step for reporting/fixing this?
