I think your example already answers the question: The query has to be 
formulated in a certain way for PostGIS to make proper use of the index, 
i.e. inside knowledge is required in order to write a query that doesn't 
break the system. This should not come from the outside.

(In addition, I am sure that one could somehow insert a sub-query that 
would delete the database ;-)
