When we did the usability studies for this we found that in practice (and 
much to my surprise) the verbosity had no impact on the usability of the 
language, so we didn't do anything to reduce it.

Furthermore, in practice, most use cases for microdata don't involve 
multiple vocabularies but a single vocabulary explicitly named using 
itemtype="", for which the vocabulary's short names are used.
