I guess it's just a matter of what you might want to use the hook for.
Some people might want to use it to short-circuit the update process.

I'm surprised you can't get the number you want, though -- the local
variable `gnus-newsgroup-unreads' should be updated in real time as you
read articles. If all you want is to do something with the number of
unreads, can't you take the `length' of that?
