A better analogy would be a new laptop company selling laptops with Windows XP.
"Our staff is more familiar with XP. We promise we're still working on the Windows 10 drivers, but in the meantime you can try to run it in VMWare."

Use the age of a service as the metric, not the absolute year we're in. It's probably reasonable to say that there is little reason not to support IPv6 for an ISP with X years of operation. Starlink is young still.
An analogy is worldwide sales for a new laptop company. You can say that in the age of globalism, there is no reason not to ship to every continent right off the bat. But for a startup with limited cash that has lot of building blocks to lay out, it's a huge risk. They should plan for it, but only branch out when they've got a solid foundation.
