Mainly that it has its complexity in the wrong places :-) (OK, I admit, I 
had forgotten about it, I have never seen anyone use it. Pragmatically, 
when something has so many use cases, yet seen very little use, it is often 
because its design is flawed).

The unit is a property of the literal, not a property of the resource. By 
requiring another node, it makes it harder to query, harder to write, 
harder to read and harder to understand. 

Also, how would you formulate a conversion between units (e.g. lb to kg)? 
Or use derived units (e.g. watt = joule / second)? That's complexity we 
should tackle, not additional triples.

Cheers,

Kjetil
