Cannot reproduce the old behavior that is mention in the PR #3635 using node v10 and nativescript@4.1.0

The issue can be reproduced only when using CLI from the GitHub repository. When you install it from npm, the package is inside node_modules and Node.js does not print the warning in such case (check Buffer section here https://github.com/nodejs/node/blob/master/doc/changelogs/CHANGELOG_V10.md#10.0.0 )
