Developers should be able to create angular applications under any node runtime using custom CLI flags

🔬 Minimal Reproduction

🔥 Exception or Error

Node.js version v15.8.0 detected.
Odd numbered Node.js versions will not enter LTS status and should not be used for production. For more information, please see https://nodejs.org/en/about/releases/.

🌍 Your Environment

❯ node --version
v15.8.0
❯ yarn --version
1.22.10

That message should actually be a warning. A fix will be available in the next version.
However, the CLI cannot be executed under an arbitrary Node.js version. It requires a minimum set of versions to ensure that the necessary APIs are present and that those APIs provide the expected behavior. The Angular CLI would crash, act erratically, and/or generate invalid output otherwise. For v12, the minimums are either Node.js 12.13 or 14.15; both of which are LTS versions.

I understand the intent. I am just trying to experiment with Angular v12 on another machine and don't want to go through the hassle of uninstalling/installing node runtimes.
I am not going to run this application in production.
