No, it is not. It is a continuation of an existing trend

You may be interested in esbuild (https://github.com/evanw/esbuild), turborepo (https://github.com/vercel/turborepo), biome-js (https://github.com/biomejs/biome) are all native reimplementations of existing projects in JS/TS. esbuild is written in Go, the others in Rust.

Its not that "deep". I don't see the politics either way, there are clearly successful projects using both Go and Rust. The only people who see "politics" are those who see people disagreeing, are unable to understand the substance of the disagreement and decide "ah, it's just politics".
