re: sensor cover glass
The thickness of the sensor cover glass as used here means the total optical thickness of the whole stack of glass layers (some bonded on, some separate layers). The total optical thickness is what matters for ray angle and lens performance implications thereof.

The numbers we report on the sensor glass is only the removable UVIR cut layers, and excludes the permanent clear cover window in the sensor itself. This layer is typically 0.8-1mm but is hard to measure non destructively.
That would make the Panasonic S1R around 2.4mm and Nikon Z7 around 2.1mm.
Leica will typically install their UVIR cut layer in place if the typical permanent clear window, allowing them to achieve the thinnest total stack.
