Sorry folks. The above 2 posts are incorrect.
Today I created the RpcAuthnLevelPrivacyEnabled DWord key again on the Server/Host PC and it does still work as a workaround.
I was able to find and add a printer on the Client PC afterward.
I will bet you dollars to donuts that I misspelled the key the first time.
Damned Lexdexia.
However, it remains that the KB5007253 update did not restore Point & Print functionality with all security intact. We still need the workaround.
Happily, I don't need to replace the win32spl.dll file to get it to work. Just the Rpc key. So that is a win, I guess.
