nodejs10 runtime doesn't work with .yarnrc yarn-path

I have no idea where I can write bugs for newer nodejs10 runtime

At nodejs8 runtime we used yarn feature yarn-path in .yarnrc it allows us to use more modern yarn vs google runtime has. (see https://yarnpkg.com/lang/en/docs/yarnrc/)

But with nodejs10 runtime this feature doesn’t work, on deployment we have error like

Cannot find module '/workspace/bin/yarn-1.13.0/yarn.js'

I created a sample project to reproduce https://github.com/istarkov/nodejs10-runtime-error

if you run there

# uses nodejs8 runtime
yarn deploy:8

project will be deployed, result at https://europe-west1-realadvisor-v1-sites.cloudfunctions.net/test-env will show that used yarn version was 1.13.0

But if you run

# uses nodejs10 runtime
yarn deploy

the result will be

(gcloud.beta.functions.deploy) OperationError: code=3, message=Build failed: {"error": {"canonicalCode": "INVALID_ARGUMENT", "errorMessage": "`npm_install` had stderr output:\ninternal/modules/cjs/loader.js:584\n    throw err;\n    ^\n\nError: Cannot find module '/workspace/bin/yarn-1.13.0/yarn.js'\n    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:582:15)\n    at Function.Module._load (internal/modules/cjs/loader.js:508:25)\n    at Function.Module.runMain (internal/modules/cjs/loader.js:754:12)\n    at startup (internal/bootstrap/node.js:283:19)\n    at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3)\nnpm ERR! code ELIFECYCLE\nnpm ERR! errno 1\nnpm ERR! test-env@1.0.0 postinstall: `yarn --version > ./version.txt`\nnpm ERR!

Please help, at least give me a direction where I can report gcloud issues and bugs, as its not the only issue I know.

Is the ability to use yarn with yarn.lock file in Node 10 engine deployed to Cloud Functions on GCP? Still looks like it is using npm and not yarn when we switch to node 10 (as opposed to node 8).

Does anyone know why it doesn’t work with Yarn v2?
