Thanks for chasing this up.
Synonym support has not fallen off our radar--it's right in the center, along with support for XML. The problem is that they all require serious engineering effort--the last major rewrite took 12 months with a six person team. That said, there is a growing demand for these issues to be resolved so don't write them off just yet.
I'm hoping to put something in place this week to make it easier for users to give weight to these types of feature request and to make sure they don't get lost or scattered across multiple forums.
