IMNSHO it's an oversight in the core JDBC design dating back to the
beginning: you have two basic choices for executing SQL.  The
unparameterized Statement or the parameterized PreparedStatement.
There should have been a 'ParamaterizedStatement' that gave the
expectation of paramaterization without setting up and permanent
server side structures to handle the query; libpq makes this
distinction and it works very well.  Of course, there are various ways
to work around this but the point stands.
