Go’s major versioning sucks – From a fanboy
>I agree with the sentiment that we should only increment major versions when making breaking changes, but more often than not breaking changes are really easy to accommodate for.Maybe on a small scale breaking changes don't cause issues, but in large-scale development, you simply can't afford to have a bunch of random CI/CD pipelines fail because a developer decided to "accommodate for" a backwards-incompatible change without separating it to a new import path.>Using different paths for different major versions makes more sense in situations where we may require two different versions of the same package, you know, diamond imports and all that. This is the exception, not the rule, and it seems strange to tap dance around a problem that doesn’t exist in most codebases.Diamond imports are not as rare as you think - it's just that you never run into it in your own code, but in the code of your dependencies. And in Go, the problem is already solved for you so you never even see the solution at work.Let's say you use two libraries for, say, backend and frontend - libbackend and libfrontend. Let's say they both depend on some parser library, say libparser, version 1.0.Now assume that libbackend upgrades the libparser dependency to 2.0, but the import path stays the same and your application - the one that has been successfully auto-updated on a CI/CD server for years and nobody remembers how it works anymore - breaks, and you have no idea why, compiler reports some weird API-incompatibility errors, and now you have to spend two weeks getting back into the codebase and debugging the issue, until you realize you can't really fix it, because the guy developing the language decided that diamond imports are "a problem that doesn’t exist in most codebases".
