It's a joke isn't it?! We spend hours maintaining that stuff and it gives the customer 0 value. :explodinghead: But on the flip-side, we get paid! :D
Mind you that's not necessarily a direct result of the tools or those using the tools. On the other hand, resources are finite. Any time used for X (e.g., wresting with Webpack) "comes out of the budget" for Y (e.g., bug fixes) or Z (e.g., a UX designer).
Clients/customers care about their users/end-customers. And users/end-customers don't give a toss about Webpack or anything else. They care about themselves. Full stop.
This is just in the nature of progress. If any product owner was fine with a simple static website which only displays some text, I'm sure there wouldn't be any noticeable bugs in it.
