Agreed. It's what put me off most OTHER outliners, and what eventually drove me from my prior organizational tool. Omnifocus, a Mac tool initially based on the well-loved (and generally excellent) OmniOutliner, had that limitation. I was looking for something where I could seamlessly co-mingle notes AND actions I needed to take, and that would then give me a dynamic view that collated all the actions for me when I wanted it.
Basically, in my imagination, I invented Orgmode and agendas, so I was super happy to discover that it already existed. That capability is weirdly rare in note tools and outliners. (I'm honestly still amazed that OneNote doesn't have this feature -- it seems like a complete no-brainer, and yet...)
Anyway, it's also a simple enough mod of the existing outliner plug-in that I'm hoping someone like me (ie, coming from org) will introduce it as an alternative plug-in. Honestly, a plug-in that would just parse the basics of org markup would be awesome -- with dataview, I don't need it to be capable of agendas or anything. I just want the markup & the outliner behavior.
