24/7 continuous recording & extended live view for all Ring doorbells/cameras please?

First of all, let me express my gratitude for finally introducing the long-awaited 24/7 continuous recording and extended live view. However, I am puzzled as to why these features are only available for the most recent Ring devices. It seems counterintuitive, as limiting these features to select devices means that existing customers who do not own the newer models are unlikely to upgrade their subscription to the new Ring services, resulting in less revenue for Ring. Economically, it would make more sense to make these features available on all Ring devices, thereby increasing the potential customer base for upgrades. Personally, I have a mixture of ten cameras and doorbells, of which only three can utilize the new features, making it impractical for me to upgrade my subscription for a feature that will only benefit three out of my ten devices. If the feature were available on all ten devices, I would upgrade without hesitation. Ring is already losing customers to competitors like Reolink, who have been offering 24/7 continuous recording and PoE functionality as requested in my other post for some time now. Restricting the new features to newer devices may compel users with older devices to upgrade their setup, but is more likely that customers will switch to competitors who already offer these features as standard. Please consider extending these new features to all Ring doorbells and cameras in the product range. If not for the battery-powered devices, due to the obvious limitations of these devices, at least for all the powered devices in the range.
