No, those are both technically inadvisable features – they aren’t impossible, but one would require a rewrite of part of Pocketsphinx that isn’t on the Sphinx project’s to-do list and the other would require a major rewrite of the listening loop.
I was really hoping to be able to take advantage of the new JGSF features.
JSGF has actually been supported since version 1.0 – the new feature is the mini-language and method for dynamically generating grammars. RuleORama uses the same language and method type, so it doesn’t represent a loss of the ability to use those new features, but I understand if you don’t want to use a plugin to accomplish your task.
