Don't really see the irony: this is just plain difficult for a machine.

To be more precise, it does it by default, but it can be turned off (by \frenchspacing). Also, in TeX, not only are the spaces after periods larger, but they also grow "faster" when justifying text (as you said). See "space factor" in The TeXbook, if you are curious about the details. (Interestingly enough, this mechanism can be hackedto achieve some other goals, too.) OTOH, Bringhurst criticizes the above style very harshly.
