I think of it as Microsoft’s OSes differentiate by features aka marketing weasels. They’re essentially the same OS otherwise. MS markets this as backwards compatibility at times as well. I think that’s a good feature that Google doesn't appear to be making a priority.

Having said all of that, I’m sick of googles abandoning of products. I loved my 2013 Pixel 7. They essentially sell goods and services only to ignore them when it suits them.
