Right now, those language options are tied to the advanced code generators.
However, bug 84739 is blocking their use.
IMHO, it would make sense to make these options available for use
with the old code generators.

Implementing for CPPWriter (C++)

SVN commit 644364 by okellogg:

Switch CPPWriter to usage of CodeGenerationPolicy and CPPCodeGenerationPolicy.
For some bug, the code generation option settings do not become effective at all.
Up next: Hunt down and fix that bug.
CCBUG:141875

SVN commit 644749 by okellogg:

CodeGenerationPolicyPage constructor 3rd arg should have been CodeGenPolicyExt*,
 this fixes the bug that the code generation option settings were not becoming
 effective, and also fixes a crash related to the codegen settings dialog.

I don't have time right now for hooking up the codegen options with
the other programming languages bug commit 644364 shows the pattern.
(In fact, this might be considered a Junior Job.)
