Can the antlr grammar be cleaned of all the Java code?

Right now I'd say it is a pretty non-standard ANTLR 4 grammar and detracts from the idea that this is a "SimpleLanguage". Most people that use Antlr use the generated visitor for compilation. For example, even a complicated grammar like for Java8 has very little (almost none except for checking character classes) Java code in the specification:

Is it a peculiarity of Truffle that requires it?
