The A, G, C, T system is apparently insufficient to completely describe the genome; See[0]. I would not be surprised if, in 20-30 years, there will be a Y2K-style "4 bases" effort to fix all software and databases to account for the missing bases; It's obvious that the extra ones play (at most) a small part, but at some point that small part might be what is stalling progress.
