At issue, I believe is a huge case of miscommunication. Folks, largely have issues explaining, logically and in a rational manner. This is very much a UI design issue.
It is important to consider that folks are generally irrational BUT mostly logical. What I'm trying to get at is that the requests and their harboring reasons/explanations lack logical deduction.
If you read the link above, there is no true logical reason why in-Timeline Grouping requires such huge attention. Zorro is cool but it lacks functionality. It provides awesome cosmetic solutions but doesn't understand why users want an in-Timeline Grouping feature/solution.
Where Zorro fails is in its context with relevance towards its functionality for the user. But then again I doubt that Zorro was meant to solve in-Timeline Grouping Functionality issues. Zorro, as we know it, is an awesome layer or gorup of layers INDENTIFICATION TOOL that does not provide in-Timeline Group Functionality.
Adobe has to put forth better questions to its users, on this issue.
I take the first para from the relevant link's relevant topic to mean that Adobe doesn't really know what it's users want - for something that most of its users have requested for. I feel that this is rather unfortunate for all involved. The (a) and (b) 'solutions' in the said paragraph have nothing to do with in-Timeline Grouping functionality
(a) has no in-Timeline functionality other than cosmetic assistance towards identifying layers
(b) this solution involves providing a function by linking information from an external composition.
Where is the in-Timeline Grouping functions that users have requested? What we should be talking about is this -> in-Timeline Group Functionality.
What we want to look at is to have a grouping feature that is based on actual functionality with respect to a layer (nested or otherwise), its KFs, Expressions and Parenting/Child structure - in essence, functionality. These are the 'tags' that users actually want when they seek an in-Timeline Grouping Feature within AE.
I could off course be totally wrong. ;-)
