FWIW, this seems to cause issues when substituting preact/hooks for react, as preact/hooks has no default export:

The requested module 'preact/hooks' does not provide an export named 'default'

[dai-shi]

That's really unsolvable from the library perspective. We hope React provides ESM, and meanwhile Preact provides CJS with default everything.
