@dreamorosi As per our conversation about making params as part of reqCtx, it might not be just those that would be affected. We might need to make changes to the RouteHandler and the resolve function as well?

[dreamorosi]

Sure, let's do it, although I'm ok to do it in a separate PR if you think this is gonna balloon too much.

[sdangol]

Yeah, I think there might be more changes than I had expected. Let's merge this one first.
