Ah ok now I get it
I did a deep dive into the whole Naomi biz and the info is scattered all over the place, so details like this are a rarity from whatI can tell

last byte in 'kaijyo?!' command reply is part of 'development boot' detection
if this byte is non zero and DES key is all zeroes -> this is 'Development security PIC' (you call it Zero-PIC), so DIMM booting process will be in special development mode.

btw first 4 bytes in kaijyo?! reply (70 1F 71 1F) is special ATA security commands, which will be sent to GD-drive and perform GD-ROM disk 'security ring' checking.

Is there a compulation of all this info somewhere?
This is again new to me

I plan on moving most or all of http://wiki.pcbotaku.com/wiki/Category:Naomi to the wiki on arcade-otaku, which is a good stable home for info
