Go moves at a pretty slow pace, adding only minor new features (and thus minor complications) in most releases. Even in 1.22, they are previewing a new feature, range-over-functions, which seem to be basically C#/Python's iterator functions - a feature which will, of course, complicate the language - but make certain programs simpler.

As a general rule, the more features a language has, the shorter program that implements a particular algorithm can be, but the harder it is to learn, and the bigger the chance that it will be misunderstood. There are exceptions where certain features make languages more verbose (e.g. access modifiers), but typically only in minor ways.
