In particular, the great thing about Pluggy is that if you have multiple handlers registered for a specific plugin hook each of those handlers can return a value, and Pluggy will combine those values into a list of replies.\r\n\r\nThis is great for things like plugin hooks that add extra menu items - each plugin can return a menu item (maybe as a label/URL/click-callback object) and the calling code can then add all of those items to the menu. See https://docs.datasette.io/en/stable/plugin_hooks.html#table-actions-datasette-actor-database-table for a Python example.\r\n\r\nI'm on the fence about relying on JavaScript modules.
