Well, actually I agree with you :-) - if the box has a memory leak, or
some other reason to force a reload, it's quite good if it comes up 
much more quickly.

I don't see any reason to "carelessly reboot" machines, though - like
what I've seen at customer sites ("this box is rebooted once per day,
whether necessary or not, it *might* cause problems if we don't reboot").

I'm not sure whether I think this makes sense.

In the standard case (access lists, AS path filters, prefix lists) the
lists can be uploaded to the running router just fine, without requiring
a replacement of the complete startup-configuration and subsequent reboot.

So even if reboots can be made much faster by this, I still want to avoid
reboots wherever possible - and it that means "invest more brains into
operational procedures", so bet it.

(I am aware that your network is much bigger than mine, but as I already
do most of these cases in an automated way, I think it can scale up pretty
well.  Exceptional cases excempt, of course)

Sure, which is why I try to avoid doing reboots at all, no matter how 
quick they are...
