I'm curious about this one, because to me reboot has always been
there to help in cases where a machine needs to be rebooted _right
now_, irrespective of what it's doing, up to and including possibly
corrupting various databases that might need more than 5 seconds to
finish their work.
It seems to me that those things only come about in the case of
imminent hardware failure, zero-day exploits against high-value
targets, and things of that nature that are otherwise unavoidable,
and that're covered by the same clauses that cover force majure in
service license agreements about any number of nines.
Out of interest, how much quicker is the current reboot compared to
shutdown -r? If you have any numbers to share, that'd certainly
have my interest.

As Warner highlights elsewhere, most people have had to alias
reboot to `shutdown -r now` - up to and including for system
processes. It seems to me that this change would mean that the few
people like you who want the behaviour will now have to do this?
For example, the x11/ly display manager I'm using lets you pick the
command to shut down the system, but it's hardcoding the command to
reboot - so if I accidentally press F2 instead of F1 (or switch to
a VTY to login and type out the command properly), it could in
theory end up being slightly annoying (since I have plenty of ZFS
snapshots to restore from.

Hi folks,
Overall, I'm in favour of making a flagday out of this, and
changing the default - because, unless you're coming from a BSD
system, you're going to risk behaviour that could be a lot more
disasterous than outlined above.
So in this instance, it makes sense to change it.
Yours,
Daniel Ebdrup Jensen
