Hi @shubh1007, this is great! I can see you grasped the problem and the strategy for solving it, thanks a lot. This will really help us to unblock some important work. Leaving just a few details, but overall looks really good.

Do you wish to continue with some other routes from this file? If so, would you push them to this PR as well or would you rather work in a new one?

Note that I'm mostly offline until July 8 - just chiming in on this issue to confirm that you can continue if you'd like, and on some days I will be available to answer questions.
