Personally, I interpret that to mean that ascended Alicorns (Twilight and Cadance) are not super-long lived (if not immortal) like natural born Alicorns (Celestia and Luna) are. The reason for this is because if the other ponies of the mane six are made Alicorns, and all Alicorns are immortal, wouldn't that just mean they'd end up missing their families as well. Though I suppose if my theory that ascended Alicorns aren't super long lived like natural born ones is true, I suppose it wouldn't cause that big a problem.

Still, I agree with Jim Miller (the supervising director for season six) when he said "five is enough" (since, in addition to the four mentioned above, there's Flurry Heart).
