 Framework kernel
 
 - [ ] Plugins declare models, migrations, routes, console commands, jobs, event listeners, admin controllers and navigation through one plugin descriptor, and can extend other plugins' models through ordinary Go interfaces and events
-- [ ] Scaffolding commands for model, controller, migration, command, job
-- [ ] i18n with CLDR plurals and namespaced keys (`vendor.plugin::group.key`), pl and en, the design carried over from summer-phrasebook
 - [ ] YAML `rules:` validation mapped onto go-playground/validator with translated messages
