That’s really not what’s going on here.

All the previous gen bundlers are written in JS and support a giant ecosystem of JS plugins. There’s no incremental way to migrate those projects to Rust. The benefit of these new bundlers is that they are literally full rewrites in a faster language without the cruft of a now mostly unnecessary plugin API.

And the “cost” of this? Some of these new bundlers are written by just 1 or 2 core contributors. Turns out with the benefit of hindsight you can make a much better implementation from scratch with far less resources than before.
