The appealing thing about not having a build pipeline is not having it. Not having another thing to maintain and update/upgrade/debug. I've gone through grunt, gulp, webpack and parcel. Somewhere along the way I realized that with es6 imports and css variables I don't really need it.

I've talked with frontend devs who only worked on projects with build steps about this and they often seem perplexed and surprised by just how simple it can be if you don't make it complex.
