With containers in mind, I was thinking it would be one or the other
not both. I can see a container only wanting an client or server
but not both.

No. 

Do we know what the container people are aiming for?  
No. I'm sure they don't know this is going on.

I really don't think we need a target size... The size 
will be smaller because how the packages are broken up. 
Installing one of the v4 packages will always have 
smaller footprint than the entire nfs-utils package.
