Example

{{ stimulus_outlet('controllerName', 'targetControllerName', 'cssSelector') }}

Yes! In fact, it’s partially done - symfony/webpack-encore-bundle#206 - someone just needs to take that work, move it here and finish it. It can be anyone - we can give credit to the original author if someone builds off of it, so that’s not a problem :)

This can be closed as this was implemented in #942 just differently
