That’s whataboutism - no language is perfect, but given when go released it’s fair to hold them to a higher standard than languages what were designed 25 years earlier.
As an aside - D, Zig, Rust, even typescript got most of the lessons learned from C right
D literally can't even maintain backwards compatibility between minor version updates not to mention a big part of the D community left when D reinvented itself with D2. Among languages it's probably the one that is constantly in a state of flux.
I'm not familiar with D, but Zig and Rust are well-known for continuously evolving.
Zig has the (in)famous "Writergate": https://github.com/ziglang/zig/pull/24329
And besides Rust's high count of RFCs, there are things like async (I'm not complaining about it, but its an obvious large-scale "change"), module system changes, etc.
(To be clear, I like both languages a lot. But I wouldn't call them slow moving or right from the start.)
