Possibility to use Describe instead of Construct in Criteria Execution

[fonji]

Hello,

Person.find(uri) will build a "Construct" sparql statement.
Person.all.resources will build a "Describe" statement, which gets way more data and so may be way slower (which is, in my case, for data I don't need).

Did I miss a CriteriaExecution option to chose which kind of statement is executed?
If not, does it make any sense? Can it be added?
I'll try to offer a solution...
