This PR allows to use all files in the dist folder if they get imported directly this is needed to allow custom builds and do some code reuse.

my current usecase is a file called:

// here i need to reimplement or access the function to normalizeOptions that i get back from the rollup.config.js

mergeOptions is an internal API I do not feel comfortable to expose TBH. Even more so for the internal batchWarnings.
In any case, the content of shared can be subject to "API changes" even between patch versions.

@lukastaegert ok so you think its better that i replicate the rollup source in my projects, or should i always make patches for rollup versions whats your opinion. And by the way for any other engine that does not care for package.json it is already exposed even as single module file if you want to produce none reuseable code maybe consider compiling some parts to binary or even v8 snapshots.

Short version

my main reason to reuse the existing code is that i can follow api changes fast and refactor fast when i maintain extra versions which i already do! it is extra none needed overhead.

While the issue that leaded to this PR is solved i still think this should be merged it blocks people from doing what they wanna do if they use a instable API why not?

whole TS tooling is build up on none exposed API's that are even more protected There is a whole community fork of Typescript only to expose the Instable API's

coders should not block coders in a open source eco system while i understand your reasoning and it makes rollup really a good product do not get me wrong but there must be a middle way.

Fun fact: Actually everything was meant to be exposed to have compatibility between Node 10 and later versions. In the "original" version of package.exports, dist/ had one advantage over dist/*: In the first version you could require both with and without extensions and it would work, while in the second version this no longer works (if I remember correctly). Now with Node 17, dist/ has become an error. So to fix this, we need kind of a breaking change, but maybe after this long time, it is no longer relevant to many, so we could just implement it.
