One of the main benefits of Esbuild (if I recall correctly) is that all passes share a single AST. Whereas in a traditional setup your linter, transpiler, formatter, and sometimes even bundler and minifier all do their own totally independent passes on the source which means parsing it from scratch each time. So this would be a classic case of integrating everything into a monolith for a boost in efficiency.
