[6.x] add event after all plugins are booted

[Anubarak]

Edit:

after a bit of tweaking we can actually use

$this->app->booted(fn() => /* do something */);

However I can imagine it might be unintuitive for developers during migration to find that solution, so I would still let this idea open as a "nice to have in the Craft 6 docs". It might be worth to think about dispatching your PluginsLoaded after the application is fully booted as well to make the migration from Craft 5 to Craft 6 easier.

Original Post:

It would be awesome to have an EVENT_AFTER_LOAD_PLUGINS event as we had in Yii2

cms/src/services/Plugins.php

Lines 287 to 289 in 61ef988

	if ($this->hasEventHandlers(self::EVENT_AFTER_LOAD_PLUGINS)) {
	$this->trigger(self::EVENT_AFTER_LOAD_PLUGINS);
	}

I know there is a
CraftCms\Cms\Plugin\Events\PluginsLoaded

cms/src/Plugin/Plugins.php

Line 253 in 97f4e4e

event(PluginsLoaded::class);

However this is called before the bootstrap process of each plugin, so by the time HasListeners::bootHasListeners is called, it's already to late and you have to listen for it in the constructor

public function __construct($app)
{
    Event::listen(PluginsLoaded::class, $listener);

    parent::__construct($app);
}

And even then this is mostly of no use since nothing has really happened at this point.
The EVENT_AFTER_LOAD_PLUGINS was mainly used to do things after Craft's default stuff happened so we can be sure all template roots are registered, all translation categories are registered, controllers paths (in Craft5) and so on.

As of now the current implementation of PluginsLoaded is nearly useless as the plugins are registered but since their boot process isn't done, you cannot access these plugins fully. Eg their component registration isn't done.

An additional event when they are all ready to use would be awesome.
Thank you very much
