India is on a separate tectonic plate to the rest of Europe / Asia.
IMO, if you're looking at continents purely from a geographic/geologic frame of mind, dividing them up based on what plate they are on makes the most sense. But, that would not take into account cultural/political/legal boundaries, all of which are probably more important day-to-day.
I've always merged. Rebase simplifies the history graph, but realistically I can't think of a time where that has been important to me, or any of the teams I've worked with.
Maybe on some projects with a huge number of concurrent branches it becomes more important, probably less so for smaller teams.
