I think it's a canary. How many languages do you hear this said about? I've only heard it in regards to Go which is fairly pedestrian (read: looks and acts something like C / Java) as far as these things go.
More exotic languages, which take the uninitiated longer to acclimate to, don't seem to be trying to tell people they're not allowed to think deeper about and question the design of the language. Good criticisms of Go were made on day 1 and are being made to this day, Rob Pike's ego notwithstanding.
At the end of the day, if I see a problem with a developing language I am interested in, I'm going to report it. If I'm met with: "I don't know you but I'll assume you don't know what you're talking about" that's a second problem and I'm not about to double-down on it.
