Lots of people pointing out how bad this is for new hires, but it’s not just a hurdle for new hires to get over… in a lot of cases people will just _never get over the hurdle_. The discussions outside their team will just be a bunch of gobbledygook that they tune out. And years down the line you end up with a really Balkanized engineering culture. Where you know what happens in Zeus, but you have basically blocked out Persephone, Ulysses, and Palmyra because they are another team’s responsibility.

Maybe that’s actually a good thing for some organizations, I know many CTOs spend most of their time trying to make cleaner separations between teams.

But if you want a culture where people understand and evolve the larger architecture from time to time, cute names are going to make that less likely.
