I'm a big fan of prefixed keys as well. If I could go back in time, I would've made my current company's API keys prefixed. Sometimes you'll chat with a customer and just notice the same isn't right and realize the key is all wrong. It's a lot easier if it starts with `company_XXXXX`. Also denoting environment (live vs test in Stripe) with a prefix is actually critical in my eyes.

I also like prefixed resource IDs. Stripe is the first one that comes to mind, but I've run into it multiple times where a customer is describing an issue and it turns out the ID they're trying to lookup is for a different resource (often similar). You don't get those accumulated hours of support time back...
