This change is likely only due to anticipation of a proposed EU law that would require 3+2 years of support, the Pixel 5a released in 2021 will only get 3 years of support, including security updates, and every single Pixel and Nexus phone that has been discontinued has had <= 3 years of support.

For comparison, all but the first 2 iPhones have received 4-5 years of support with the iPhone 6S being the oldest iPhone still receiving support almost 8 years later.

Android has been a complete joke when it comes to software support for older hardware, it's almost sad that it took proposed legislative pressure to change this.
