Indeed. There are some past discussions of this. The challenge is that 
for all the on-disk stuff people have to maintain not only backward but 
also "forward" compatibility; you can't do things like add a possible 
value of a gconf key that will break older versions of the program.
Unfortunately it's very hard to be sure nobody introduces any bugs of 
this type, in any application, between any of the possible combinations 
of GNOME versions... it's good to remind people of the issue and try to 
minimize the bugs, but without a pretty extensive effort to QA the 
behavior of GNOME releases in this context, I'm doubtful it will 
reliably work to mix arbitrary GNOME versions with a shared homedir, 
sadly. It's very easy to break this accidentally and in each release 
there are many changes people make that are likely to break it.
