In other words, why would anybody wish to implement a language with Truffle on Java7 if the performance gains offered by Graal’s partial evaluation and deep inlining are not available there?

At the moment, this is mostly for the benefit of the JRuby team. They want to distribute JRuby’s invokedynamic implementation together with JRuby’s Truffle-based implementation. For the overall jar, they prefer Java7 compatibility.
