When it came to the notorious split infinitive (e.g., “to boldly go where no man . . .”), [Fowler] observed that those English speakers who neither know nor care about them “are to be envied” by the unhappy few who do.

Not to even touch the fact that that proscription is not reflective of actual English as she is spoke–so it’s not even a real rule, but merely a grammarian’s hobby horse.
