Agree. You also can't enjoy most of the benefits of status without flying (and thereby earning more status credits to bother retaining), so it makes sense to incentivise both spend and experience of those benefits. If you're not flying the airline, who cares if they extend your status? If they extend it and you fly anyway, you're still earning the credits.
Additionally, sure, it's nice in principle to see my QF status extended, but the fundamental problems at QF haven't been fixed and fares continue to outpace competitors in virtually every market, so it won't mean much of a thing to me in practice. It's "nice to have," but not worth paying thousands of dollars more across all my travel.
The double SCs for an extended period without arbitrary chance booking windows was also a brilliant strategy. VA was clever with their DSCs on all flights from earlier this year and last. It helped me earn Gold almost accidentally while simultaneously actually experiencing the service and value proposition to decide it's worth it. (Though truth be told, it only took one experience of experiencing the ease of the Travel Bank to convince me when restrictions were still on across the country.)
I'll manage to get the rest of the way to Platinum over the next few months, and with VA's easier retention and soft landing policies, I'm committed to them for the time being and booking my forward int'l bookings with their partners. Coupled with my Star Gold status, it's easy to let go of QF. I'd love to see more expansion and reciprocity of loyalty recognition across VA's international partners, but at the end of the day, what I don't get at VA isn't worth the added cost at QF. Simple as that.
