The thing is, what the "best" tool is, is relative to your requirements. I much prefer "Use the right tool for the job", as it makes it less cargo-culty and emphasizes that it's not always right.
For example, if your build process is very slow and you for some reason have to have it be very fast, esbuild is probably the right tool.
But if instead your goal is to build a large community of developers who can change their own tooling, webpack is probably the right tool as it's by JS developers, for JS developers.
Overall I agree with you, just nitpicking a bit I guess :)
