No, HTTP2 doesn't just replace bundling, and definitely not what Webpack does.

Based on what I've read, sending a few bundled chunks instead of many individual module files will still generally have less overhead. In addition, Webpack's ability to load and transform other file formats like images and styles is something that simply requesting ES modules over HTTP2 can't deal with. Webpack's ability to code-split an application is also important.

Tobias Koppers, the main Webpack developer, wrote an article last year on how Webpack and HTTP2 relate: https://medium.com/webpack/webpack-http-2-7083ec3f3ce6 .

It's also worth noting that Tobias had only been able to work on Webpack intermittently for the last couple years, until this recent funding allowed him to work on it full-time. Tobias has been writing reports on what he's been doing [0]. Also, grants and full-time development is enabling the team to work on projects like integrating WebAssembly support directly into Webpack [1].
