Short names make sense if they are easily understandable locally: This means either something extremely common throughout the codebase (I think the most common example being localisation wrappers for string literals. They should ideally be linked to a more clear explanation easily, e.g. from renaming import statements), or defined (clearly) and used only within a very small area of code. This API is neither of those.

Short names also make sense if the same conventions appear over and over throughout the code base. While they can be quite opaque at first, they're very consistent, and people with experience in other APLs will recognize many of them.
