What happened to the "Enable Nested Modules" option in m2-eclipse?

The thing here is the option to enable nested modules was moved to the Window >Preferences > Maven. Set the Support multiple Maven modules mapped to single Eclipse Workspace project checkbox, right click your project, navigate to Maven menu item you can find the 'Enable nested modules' option.

Looks like support for this feature was recently removed:

https://issues.sonatype.org/browse/MNGECLIPSE-2291

Why did this option disappear? Is there some newer, better way that I should be using m2-eclipse to find nested modules?

Could this be somehow related to the option below (accessible via Windows > Preferences > Maven):

To be honest, I'm not 100% sure because I don't create my projects under Eclipse, I create them on the command line outside Eclipse and import them as Existing Maven Projects (and this works with nested modules).
