The reason these are not currently in the game is indeed that they would be very small compared to other provinces (and it's also not that clear that, for instance Diu, would actually have to be an important province in the first place in an alternate timeline). Still, if we ever were to expand the province count in India in general they would definitely warrant a second look. 1.20 will be a patch focused on East Asia though and so it won't have any map changes in India 
This comment makes me quite nostalgic
I believe it's the first time I hear it since the Art of War overhaul of the Non-European world (and where I was the one to overhaul the then much less detailed India).
