There is currently a huge gap between Agave and COM-based add-ins.
Hybrid add-ins are the way forward to bridge that gap whilst the API set matures in the coming years.
As a developer community creating innovative solutions focused on making the most out of Microsoft Office apps, we need to be able to give users the option for a web-based add-in across all endpoints and provide them with the ability to switch to a desktop experience to access a wider set of features. This mirrors the approach taken by Microsoft with the "view in browser / desktop" experience.
There are currently three areas which are missing to make hybrid a reality:
1. The ability for COM/Agave add-ins to share the ribbon
2. The ability for COM/Agave add-ins to invoke each other
3. The ability for COM/Agave add-ins to talk to each other
Note: when I refer to COM, I mean the Common Object Model for Windows and macOS, not the Windows-only COM/VSTO technology.
Please please make this happen!
