Are IOS XR upgrades still such a pain today?  (We never moved to XR64,
and all I know is ASR9001, where the fastest way to do major upgrades
still is "turbo boot" with 2+ hours of downtime...)

This is one of the nice bits about IOS, IOS XE, EOS, etc. - "upload one 
image onto the box, reload, upgrade done" (and on EOS, the flash is
actually fast enough to make the "upload" really use available bandwidth
to the box...)
