BQ25700A: Dead Battery support (Instant-On With No Battery or Deeply Discharged Battery)

Part Number: BQ25700A

Hello,

Wanted to ask for correct implementation of BQ25700A  for Dead Battery support.
There are few points that I would like to check.

I am going to use back to back FET's like in bq25700AEVM-732 for inrush current control and USB port Vbus separation from large capacitance:

But I have one problem here:
Before connecting input voltage I don't have 3.3V to pull up CHG_OK. 3.3V will be available later after device is turned ON. But I get around 1.19V on Q9B base that comes from 3.3V bus where it is being injected most probably from REGN over JP5. This makes impossible to allow current to flow through back to back FET's and start Wakeup charging.
Could someone help with correct solution for proper initialization of powered off device charging?
I had idea to pull up Q9B base and CHG_OK from separate 3V LDO that gets power from REGN and 3.3V through diodes so this LDO will be powered only after Vbus connected.

From datasheet ("8.6.5.1 System Voltage Regulation") I read that if I remove BATFET then configuration over I2C is needed. This means if battery is fully depleted and BQ25700A registers are reset to defaults due to power off and I can't charge battery because I can't configure BQ25700A.
So if I need to design product that needs to have "dead battery charging" I can't remove BATFET? Is it correct?

Maybe there are some more tricks that I need to consider for Dead Battery charging?

Thanks,
Kristaps
