Geologists Like Their Eras Longer?

Humans are having a profound and growing impact on their only planet. This species is responsible for a record number of extinctions. It's also in in the process, after 11,700 years, of bringing the Holocene's stable climate to a rapid end. Humans have also changed much of the Earth's dominant fauna and flora, as well as leaving plastics and radioactive isotopes in new deposits. Humans could be said to be having as much impact on the planet as the asteroid strike that 'did for' the dinosaurs. It's been suggested we should recognise this fact, by creating a new Geological era, the Anthropocene. The International Union of Geological Sciences have, however, in a series of votes, rejected this suggestion (https://www.theguardian.com/science/2024/mar/22/geologists-reject-declaration-of-anthropocene-epoch). Some what strangely, The International Union of Geological Sciences acknowledges that "The Anthropocene is a concept that will continue to be widely used by Earth and Environmental Scientists but also by social scientists, politicians and economists, as well as by the public at large". What they seem to be saying is, "everyone else can use Anthropocene but we don't want to". Perhaps it's too short and fast? If humans drive themselves to extinction, along with many other species, there'll be nobody left to worry what geological era it occurred in!
