If I'd seen a Balloon2 boot from NAND, I'd be more tempted to
leave that functionality in. However, it's tricky, untested, unproven,
and not necessarily even possible.
If it worked, and I could be sure that leaving the boot Flash off the
board was safe (saving board space and routing resource), I'd be
tempted. As it is, it's unproven, so I'd have to still fit the boot flash
to the board. The only benefit would be that we could no-fit the
boot flash once NAND-boot worked. That's a small cost saving -
nice, but no more than that. (And, to be honest, I'd like Balloon to
be bootable by conventional bootloaders, too. NAND-boot is
going to be very tricky, even if it works.)
