when running it locally instead of default export - whole module is imported here

It's expected, because @babel/traverse is not a native module but it's compiled to CJS.

I wonder if we could speed this up with
for (const [importSource] of source.matchAll(/(?<=from\s*")@babel\/[^"/]+/g)) {
result.add(importSource);
}this doesn't work for generic JS, but it should be ok for our own source files.

that actually not only faster - it also covers additional cases when when having export {} from "" statement

I cannot reproduce the failure locally, and GH doesn't let me clean the actions cache. Could you try rebasing this on |

Approving, pending the revert of 5648962.
Note for other reviewers: the reason this is needed is that relying on devDependencies introduces many circular dependencies between packages, and TS doesn't handle them well. What this PR matches is a subset of actual deps/devDeps, because many devDeps are only used in tests.
This reverts commit 5648962.
