I tried this at the time, lots of published types (or their @types/* packages) need updating at their end 😭

For example, the commonjs Rollup import will error with:

This expression is not callable.
  Type 'typeof import("/path/to/project/node_modules/@rollup/plugin-commonjs/types/index")' has no call signatures.

Although you can sometimes use named exports to avoid the issue like here:

  import commonjs from '@rollup/plugin-commonjs'
- import resolve from '@rollup/plugin-node-resolve'
+ import { nodeResolve } from '@rollup/plugin-node-resolve'
