UPDATING as far back as stable/10 (= 4 major updates) is a little bit  
excessive (more than 9 years of development work so far), isn't it?

I don't get the "more than just src updates" part. If we don't talk  
about the source code, isn't src/UPATING not the wrong place to store  

In terms of updating products, I understand that updating them every 2  
years may be a little bit expensive/excessive for some vendors, but  
taking every UPDATING from every stable branch in-between doesn't look  
too much time consuming to me. And compared to the huge amount of  
changes between N-2 and N... taking UPDATING from all stable branches  
in-beteen is nothing. Nevertheless, 4-5 years I consider OK-ish,  
nearly 10 years is ... ugh ... a life-time or two in the computer  
world. If we look e.g. at the PlayStation (yes, just one of the  
products which has FreeBSD inside, but personally I consider it one of  
the more stable ones than some network products which have a shorter  
shelf-time than the PS-line from an OS-version-tracking point of  
view), there are around 6 years in-between models, and they surely  
haven't started developing a month before the release date.

So where do we draw the line for UPDATING, 2 major versions (~4  
years), 3 major versions (~6 years)? ~10 years (~5 major versions)  
looks overly excessive to me. That's not something you want to try to  
catch up, that's rather a new development than a catch-up.
