The short version
- Each has a real cost: GNU Emacs steep learning curve for its default keybindings and Lisp-based configuration.; Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
- They diverge on capability: GNU Emacs covers Emacs Lisp Extensibility, Rollup covers Tree shaking.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
GNU Emacs
- Steep learning curve for its default keybindings and Lisp-based configuration.
- Default UI looks dated compared to modern editors without heavy customization.
- Performance can lag on very large files compared to newer editors.
- Discoverability of features is poor without prior familiarity or external guides.
Rollup
- Slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
- Application concerns like dev servers and hot reloading are not its job, so app builds need Vite on top
- Configuration for non-trivial applications gets verbose compared with tools that assume more
