Agree 100%, ditto for suggested alternate name. I'd been doing the same for Rust. It's not a rational reason, sure, but I have to sell adoption to a broader userbase that cares about more that the technical merits.
I don't want to have to make the case for why someone's system needs rust and cockroaches.
I have to say, I think that if you have a problem with "Rust" then you lose credibility in your criticism of "Cockroach".
Contrary to most above, I think "Cockroach" is great. It's suitable. Any suit who has a problem with it should get back on their side of the office, and stop sticking their nose in things they know nothing about, especially when so evidently closed minded. There are too many people in that meeting. Hell, even "Google" is a crap name, sounding like a baby word, and "Mongo" can be outright offensive. I expect anyone who has an issue with the name "Cockroach" is probably not going to be too open to the cutting edge anyway, so wasted concern.
