While I agree with you, I think you underestimate the number of features that help Rust be great in the face of a Lifetimes and Generics. One feature tends to lead to another. For example, Traits with Associated Types are amazing, but they then lead to a desire for GATs. GATs aren't (in this context) some fancy feature of its own, it fills in a noticeable void in an existing feature, Traits.

So many of these features Rust adds just fill in holes in an already extensive ecosystem.

I agree some feature development could be toned down to mitigate the moving target problem.. hell I think last years poll expressed roughly that. But, I think there's still a ton of features yet to come that merely complete what we already have.
