None of the humans ever comment on their use of Gender-Blender Name, despite knowing the historical source of their names. It's unlikely that the Krakau would make any attempt to hide that Marilyn Monroe was a female actress, for instance. However, the Krakau are a One-Gender Race. The concept of gendered names is likely completely foreign to them, which means it's foreign to their reborn humans. In the second book, Mops gives a male alien the nickname "Kate" not as a joke but because she saw nothing feminine about that name.
