With Google changing the game for everyone on 31 May 2021, when I check the videos I used to download, I can now see a message in the developer tools console tab:
Can't verify license request signature; either the platform is wrong or the key has changed!
The public 2048-bit RSA key Widevine uses for Chrome devices in L3, on Windows
`-----BEGIN PUBLIC KEY-----
-----END PUBLIC KEY-----`;
// The private 2048-bit RSA key Widevine uses for authenticating Chrome devices in L3, on Windows
// Extracted by applying some mathematical tricks to Arxan's white-box algorithm
`-----BEGIN PRIVATE KEY-----
-----END PRIVATE KEY-----`;

The public and private keys that you are referring to are associated with chrome 1610. The question is, have they been changed for the new CDM or are they the same with more obfuscation? These are the unknowns.
The answer is no. To get this to work again, you will have to modify the eme_interception.js and the content_key_decryption.js files.
I've found some information regarding this using openssl but it's way above my knowledge level, but would be interested to know what others experience is.
Maybe you can share this info with the community or myself so that it can be evaluated.

Can someone post, hypothetically, what would need changing in the old extension besides the public and private keys in order for it to work again?
To make extension work again you only need to add new working chrome cdm RSA private keys.
