Just saw this on this year's Octoverse:

Frameworks ship with TypeScript by default. Next.js 15, Astro 3, SvelteKit 2, Qwik, SolidStart, Angular 18, and Remix all generate a TypeScript codebase by default (npm create, pnpm dlx, or bunx create).

Should we follow the trend?

Node.js supports stripping TypeScript syntax by default since v22.18.0. Vite supports.ts out of the box. I guess the infrastructure is mostly ready.
