Owen, While I know you are a smart engineer and obviously have been working with this gear for a long time you're really not adding anything or backing up your argument besides saying yet again the packet forwarding is different. While this maybe true..It's my understanding that enabling packet mode does turn it into a normal packet based junos. Admittedly I have limited experience with turning these branch devices into pure packet mode so instead of repeating the same thing over and over why not provide links and other documentation showing the difference?

I find it humorous that you think J/SRX junos isn't real junos.
If it runs JunOS, then yeah, it's real JunOS. It might not have the feature you're looking for, but that's something different.
No, it's not. Flow mode is NOT packet mode and it doesn't really ever run packet mode in the current version. This has fundamental and significant impacts on the way packets are handled when being forwarded through the box which come with side-effects that cannot be overcome by mere configuration changes.
The Juniper ERX edge routers are what isn't "real" JunOS. It's as if they were trying to make a clone of the IOS CLI:
Those are not JunOS at all. They don't really try to pretend to be.
The SRX and J-Series Services routers, OTOH, are most definitely pretending to be JunOS while not behaving like JunOS at certain fundamental levels.
