I would not bump yearly just because we can. If some development is 
actually blocked by limited ABI or it would be too much work to maintain 
something, then OK, but in general IMHO it is better to keep the number of 
ABI versions small. (less stuff to maintain, less number of versions of 
libraries for distros to ship, etc). So the current 1-2-3 years as it 
fits us looks fine by me.
