I think we have a bad merge into the 15 branch. This is very likely failing

Do we need to set everything to false or can we just not provide the fallback config?

Honestly it isn't entirely clear 😂 . The recommendation AFAIK is to set the fallback to false. What I have noticed, though it isn't documented, is the polyfills sometimes make their way in when you don't specify a config and they just happen to exist in your node_modules directory. But that might be a side effect of something else

Additional details
With the release of Cypress 15, we are removing the default built-ins from the
@cypress/webpack-batteries-included-preprocessoras they are usually not used by end users within their cypress tests and bloat the user bundle. This is also to reduce security vulnerabilities introduced by the built-ins.Note: some tests needed to be pulled out into their own directory to prevent cross-pollination of the build-ins in the cypress config. Hence why the screenshots test and the node built in test were both moved
Steps to test
If wanting to use the built-ins, set up a project that has references to
pathwithin your spec file. notice the test fails because path is no longer provided by the preprocessorHow has the user experience changed?
