   NPM VERSION WARNING
 
-  Issue a warning if not running with npm 8.5.5, since the errors
-  that you get if you run a different version are not very obvious.
+  Issue a warning if there's a version mismatch between expected and user's
+  version of Node or npm, since it could cause strange difficulties.
 
-  - Help contributors who switched their Node version inadvertently.
-  - Support new contributors by printing more context / steps to remedy.
-  - Give the benefit of the doubt to developers who run a different node/npm
-    version on purpose. So, don't process.exit(1), even on npm install.
+  It is a bit redundant with the EBADENGINE warning issued from package.json,
+  but this script (originally written for a bumpy >=16.15.1 upgrade) provides
+  a bit of context.
 
   Show on preinstall. Since it's easy to miss there, also show it on other
   run scripts such as 'watch'.
