HATs and other add-ons • Power HAT+s specification

Hello
I have a question regarding current(2024-10-10) Power HAT+ requirements.
There is no way to build intelligent "Power" class HAT+ reporting to CPU information such as battery SOC, charging status, current consumption, etc., because according to the class description:

HAT+ that provides sufficient power for ...., that does not electrically connect to GPIOs 2-27

Using the "Standard" class for intelligent HAT+ providing power via GPIO header instead of "Power" is possible but will prohibit use in combination with any additional useful "Standard" class HAT+.
It looks like the current HAT+ specification makes it impossible to build typical configurations like:
"Power" HAT+ provides battery power and status or functioning like UPS and another "Standard" HAT+ with GPS/CAN/modem/etc.

I would like to hear the engineering staff's comments on this topic.

Thank you in advance
