Would this conversation be portal-based data, or a view of something sourced elsewhere?

My initial reaction is to be a bit nervous, so I tried to make this into a more concrete example. Imagine a conversation occurring in the portal around a new component being proposed for a Github-based repository (versus as an issue or pull request feedback within that repo in Github). Having that discussion solely in the portal feels like it could potentially lose context and/or duplicate conversation going on in the source system (or in a work/bug tracking system if your code repository system of choice does not support that conversation in the same way that Github does).

Sharing early wireframe, happy to get your feedback
