I have briefly looked at the Reaper codebase but I am yet to analyze it better to have a real, meaningful opinion. 

My main concern with starting with an existing codebase is that it comes with tech debt. This is not specific to Reaper but to any codebase that is imported as a whole. This means future developers and patches have to work within the confines of the decisions that were already made. Practically speaking once a codebase is established there is inertia in making architectural changes and we're left dealing with technical debt.

As it stands I am not against the idea of using Reaper's features and I would very much like using mature code that has been tested. I would however like to propose piece-mealing it into the codebase. This will give the community a chance to review what is going in and possibly change some of the design decisions upfront. This will also avoid a situation where we have to make many breaking changes in the initial versions due to refactoring.

I would also like it if we could compare and contrast the functionality with Priam or any other interesting sidecars that folks may want to call out. In fact it would be great if we could bring in the best functionality from multiple implementations.
