India was never a part of SWMH's map extension plan. The plan was already in the works before Rajas of India came out. Then came along Rajas of India, which created the expectation that SWMH, too, should include India. As a compromise, elvain, who was responsible for the Middle East and eastward, decided to include only northern India, his justification being that at least this part of India interacted with the rest of the CK2 map (for example, see the Ghaznavids).
This eventually led some people to think that SWMH "removed" or is "missing" much of India, but you see how that line of reasoning is problematic: SWMH never planned to include India, so SWMH never really "removed" India in the first place - what actually happened was that Rajas of India added India all of a sudden, thus creating a crowd that wanted to see India in SWMH.
That was more of an explanation on the circumstances, but no, the SWMH team is not considering adding any more of India.
