Measurements posted indicate that the difference between deep and s2idle is minimal, though, and possibly within the margin of error. Are you basing your reminder on specific hardware configurations where the difference is significant?
My main motivation to retest was to verify the claim that the USB-A problems had been ameliorated: Passifying the USB-A Card - #30 by nrp . While s2idle performance across the board does seem to have improved, it seems the “penalty” for having a USB-A plugged in hasn’t changed. This makes me think the improvements are due to improvements in the hardware support in the Linux kernel; not in the firmware updates.
