Short review: I like the idea, but this needs some work. If someone is still wanting to work on this, i can give a full review.

I can work on this.
@geek-merlin: What exactly needs to be done?

Re-rolled the patch for 3.x.-dev.
There was a change in the function determineBundle introduced in 🐛 Wrong bundle form is displayed if user has permissions to create only one of the available bundles Fixed .
It is now using $this->getCreateBundles() instead of $this->getTargetBundles() to solve the issue of user permissions to create certain bundles to be respected. Passed $context as variable to the function to allow for the API call.
Works now as expected. Please review.

You are lifesavers!

I tested the inline_entity_form_entity_save hook so far, and everything works great. I took the liberty of creating an issue fork, just to clean up some warnings raised by PhpStorm (nitpicking mode on 🙄).

Once I test the other hooks, I will update the status to RTBC.

Tested with latest D10.4. All good, thank you. Converting to RTBC now.
