No, because layers of abstraction come at a cost and we have created a temple to the clouds piled with abstractions. Any option to simplify processes and remove abstractions should be taken or at least strongly considered.

Code written for a web browser 30 years ago will still run in a web browser today. But what guarantee does a build step have that the toolchain will still even exist 30 years from now?

And because modern HTML/CSS is powerful and improving at a rapid clip. I don't want to be stuck on non-standard frameworks when the rest of the world moves on to better and better standards.

Having all your code go through a multi-step process that spits out 30 different files makes it impossible to know what’s really happening, which I’m uncomfortable with.
