The 'replacement migration' concept is definitely under perpetual discussion in the UN, as evidenced by the link. It's a popular concept among some groups, and has some very controversial 'anti colonialist' elements. This strategy did not make it's way into the most recent UN compact on migration (I believe because it would be untenable under current populist conditions) but it's definitely a perennial subject among those types of officials. Unfortunately, there are a lot of conspiratorial elements out there concerning this, but there is a basis in reality for this agenda.
