Allow rendering view modes instead of menu links (submodule)

Problem/Motivation

Hey, this is just a proposal for the far future, but I think it makes sense to discuss this.

Some days ago I came across entity_submenu_block module, which allows rendering the submenu level of the current page as entity view modes. It has some further options, but that's the key functionality.

As a user of menu_block since ever, I soon thought, this would be super powerful if it would be built on top of menu_block to combine the functionality!

While menu_block allows selecting the levels to render, title, etc. a lot more, entity_submenu_block provides settings to show rendered entities instead of text links in the menu block.

A menu_block submodule, e.g. menu_block_entities (or sth.) would implement the functionality, it would solve the existing functionality plus for example:

• Render sibling menu items as entities
• Render multiple menu levels as entities
• Render a selectable menu tree as entities
• and that all combined with the title linking etc.

Together, that would be able to solve even more use-cases, which the modules can't solve stand-alone.

So what do you think about that? Should we implement a menu_block submodule based on entity_submenu_block? And what should be the name?

Happy to discuss!
