I actually stated this on the post, but let me reiterate, I think that naming things in somehow fun way is totally okay as long as it stays relevant to what the tool actually does (you can have this achieved by play wording suffixes (Mongo"DB", Open"SSL", Ma"git" are good examples, all are better than elephant, dog, and beaver).
Namespacing, sure. But is "We use gh:someguy/openai/llm-streaming-client to talk to the backend" (x50 similarly cumbersome names in any architecture discussion) really better than "We use Pegasus as our LLM streaming client"?
This is one of those classic examples where things you've already learned are "obvious and intuitive" and new things are "opaque and indistinct".
We can go back and forth with specific examples all day: cat, ls, grep, etc are all famously inscrutable, power shell tried to name everything with a self-documenting name and the results are impossible to memorize. "llm-stream" tells me absolutely nothing without context and if it had context, pegasus would be equally understandable.
