Go recognizes the arrogance of language designers (Pike is a team member, so it was hard for such a thing to go unnoticed!), hence why they put their theories to the real-world test instead of just guessing. Most languages seem to pack in feature after feature because some random nobody on the internet thought it would be a good idea without ever seeing if their thought could be proven as a good one, but Go tries to actually show it first.
Which is also why it draws so much ire. It speaks the truths developers don't like to admit.
"Enterprise" being a euphemism for low-quality developers who don't know how to write quality software (the sloppy developers referenced in an earlier comment)? Perhaps not. Go does seem to scare off anyone who relies on crutches to work around shoddy work and inability.
But it doesn't really matter which codebases they used, does it? Replication efforts will reveal anything they got wrong. No need to make guesses.
I have written, and continue to write at another org, Go that drives line of business software that makes billions of dollars and runs the real world. Check a random email you have and if you see a header X-EID, it was processed with Go.
Individual codebases can already include stack traces as they see fit, so studying only a single codebase would be rather pointless. If an individual codebase benefits from stack traces, it will use them! The study looked at how often they were used to determine if it would be a useful default. It found, by looking at many different projects that had stack traces included by default, that it would not be useful to include by default. Especially in light of the cost of inclusion. Adding stack traces is definitely not free.
"Enterprise" traditionally refers to code that is full of bad practices. Like, when Java was all the rage, FooFactoryBuilderFactory was the embolism of enterprise. In other words, where sloppy developers are found. Glad we were able to clear up that isn't what you meant.
So you are meaning – with respect to the code – the same as all other software? What, then, is "enterprise" trying to add? It is not like you would write code that makes billions any differently than you would a code that makes a dollar.
Which is also why it draws so much ire. It speaks the truths developers don't like to admit.
