The list covers only official proposals (proposed by ISRO or IIA personnel at some point of time). Timeline may be shifted towards very long delays as research barriers or launch failures aren't being assumed.
Further, to launch Gaganyaan M1 in 2022, we need at least 7-8 launches of GSLV MkIII between 2022 which I don't think is practical and mission might get delayed.
BTW, keep posting above list with updates (only upto 2025) after every update. That's how we are going to run this thread.
