I'm not sure about this. Node 14 is in "Security support" maintenance mode (https://endoflife.date/nodejs), which to me means that it hasn't EOLed yet. We still support it in Hardhat, for example (this is our policy).

Fair enough.
I'll add 18 to the github actions though

Which version of npm are you using? Just curious about some fields of the package-lock.json being dropped after it's converted to lockfileVersion 2.

the package.log was generated using npm 6.14.13 which is the version that came with nvm use 14
I found it interesting that that the file changed so much so I redid the process and the file size wen't back to lockfileVersion 1.
