That's been the case with hardware at several companies I was at.

I was convinced that the process was encouraged by folks who used it as a sort of weird gatekeeping by folks who only used the magic code names.

Even better I worked at a place where they swapped code names between two products at one time... it wasn't without any reason, but it mean that a lot of product documentation suddenly conflicted.

I eventually only refereed to exact part numbers and model numbers and refused to play the code name game. This turned into an amusing situation where some managers who only used code names were suddenly silent as they clearly didn't know the product / part to code name convention.
