Yes, simplicity is more practical.

Problem in _requiring_ any specific serialization is that it enforces 
specific complexity of the involved systems - publishers or consumers or 
both.  Publishers and distributors and consumers each want certain 
simplicity - but it is not the same (else we would have no debate for 
these many years!).

Having no default but only recommending JSON-LD would not block you from 
publishing Linked Data serialized as Turtle.

Same as western establishments recommending US dollars as reference 
would not block east asian communities to use Chinese Yen as reference, 
and anarcists using Ether.

My point is that the World is complex, and best we can do is encourage 
simplification, enforcing it won't help and might cause more damage.
