I'd agree in general, but they copied the other rule about falling into liquid off the same page from Tasha's without modifications and not the rules for falling onto other creatures.

They specifically chose not to have those rules when it would have been no effort to add them.

And they did update falling, by adding the section about falling into liquid, and describing it as a hazard.

That signals to me they very clearly did not want those rules as the new baseline for the game.
