No. Qi never (except when the battery is deeply discharged or on gta01
that lacks leds and vibrator) silently exits.

That's obviously not true. Read again about AUX led and vibrator
feedback.

No, the feedback provided by Qi is always present and always identical
(unless you have a very discharged battery, in this case feedback is
disabled).

Qi takes about 2 seconds to boot the kernel. After that it can do
_nothing_ "to reassure the user" because the control is transfered to
the kernel. The same with u-boot.

You use Qi only for 2-3 seconds on boot. And it provides feedback
during that time. Period.

If you like u-boot, go ahead, hack on u-boot. But don't think that
someone else must do that for you.
