I disagree based on my personal experience. The CPU upgrade path for my current desktop computer ended roughly a year after I bought it, even though that CPU generation had been introduced very recently by Intel. I got a relatively high-end CPU, so upgrading to anything but the highest-end CPUs of that generation doesn't really make sense from a performance point of view. Yet those still cost a surprising amount of money today and offer worse performance than the midrange options of newer generations.
Simply put, extending the lifetime and thus upgrade path out by at least 150% means that the options available 5 years down the line will be 150% "better", even though no CPUs for that socket might even be in production anymore at that time. For me that seems like a significant advantage.
