I agree. I've worked in places that discourage "cute" names and the result is often things like having to decide between using CoreMainHttp and MainHttpCore. Or worse, two things with exactly the same name, but two different APIs, with projects sometimes taking both as a dependency at the same time. Or even obsolete parts of the org chart encoded into dependency names, like "DataOrgUtils" when the "Data Org" stopped existing several reorgs ago, when our current VP was an intern and nobody else even worked here.

Without some central control of names though, even "cute" ones tend to converge on the same handful eventually: Phoenix (and other classical allusions like Plato's Cave, etc.), Keymaster/MCP (and other 80s childrens' movie references), Simpsons characters, Star {Trek,Wars} references. These are all attractors for the kind of people that tend to be in IT/SWE even if the actual namespace (all possible ASCII-expressable words) is much larger.
