Thanks to Scaffolding REST API, power users and developers can update Scaffolding data programmatically.
When updating Scaffolding values via Edit Content, a user is presented with an option not to notify watchers. This option is not available when updating via REST API. For pages that are frequently updated via Scaffolding this causes a lot of noise for Space and Page watchers.
Same as for Confluence page REST API, a "minor edit" option is needed to allow for the changes to be made silently.
