I've been reading comments about the T2 chips and how they might be used to kill Hackintosh, but wonder if there isn't a parallel to custom orders without cameras and microphones for highly secure locations (national intelligence locations, for example). Having read about companies ordering computers without any of those hardware features makes me wonder if there are contexts in which the T2 chip would need to be disabled in order to be allowed on site.

Being able to boot from older backups could be key in some production locations in which someone needs to access an older application no longer supported in newer OS builds. It appears the T2 chip locks the system from external booting by default and would require changing the setting to allow for such: https://support.apple.com/en-us/HT208198

If so, might there be a boot switch disabling the T2 chip altogether? Wondering if anyone who better understands the variety of contexts in which these system might be used has an idea of why the chip's security features MUST be allowed to be turned off in order to be used. Apple certainly isn't going to give up thousands of orders, plus with the rise of their services (iTunes, iCloud, etc) as major income streams, killing the Hackintosh option would certainly cost them money as well.
 
Wesley Faulkner at IBM explains some uses of the T2 chip in this week's This Week in Tech. Sounds as though Apple if creating hybrid systems offloading processes such as encryption to the chip in order to minimize load on the primary CPU. If so, then the operating system might eventually not be designed for a single processor system and slowed as a result. He also opines on the roadmap to shift from Intel to Apple's own chip designs using the T2, though I suspect that is many years away.
