Thank you.
You know, I couldn't for the life of me make sense of replies like "The update is not applicable to your computer".

An answer in perfect accordance to article 4569557 was given, but no success???
So I tried to break Windows Update by removing KB4474419. Nothing happened.
Ran Windows Update on a fresh virtual installation of Windows 7 SP1 - found updates without making any preparations...
I know that both updates become indispensable going further, but Microsoft's claim of "Will be impacted" regarding Windows 7 SP1 is just plain incorrect. Windows 7 SP1 has experienced no change at all by the 2020 SHA-1 endpoint discontinuation.
Also note that it just makes no sense advising to fix Windows 7 RTM and SP1 the same way.
