How to completely get rid of bundles in symfony templates and translations?

Question

symfony

At the suggestion of the esteemed Sergey Protko , he decided to use this approach in the application: elnur.pro/symfony-without-bundles
This is especially convenient after the number of bundles exceeded 10.
Everything is fine, but I can't figure out the templates and translations.
Now this is the structure:

The question is this.
How to completely get rid of bundles in templates and translations?
For example, now in the controller you have to write crutches like :Dashboard/Security:login.html.twig I would
like to rewrite this case so that all templates are loaded like this: Dashboard:Security:login.html.twig
so that in the Backend:User:list.html.twig template you can write {% include '_list-item.html.twig' %} instead of {% include 'Backend:User:_list-item.html.twig' %} (in short , as in Yii).
With translations, I’m still worse: I still haven’t figured out how to make such a structure work (as in the spoiler above).

Answer 1

For example, now in the controller you have to write crutches like :Dashboard/Security:login.html.twig - why do you think this is a crutch? And if you need to load a template from somewhere else, how do you do it with your structure?
