could we add access to fuse_get_context() ?

I was thinking about a decrypting filesystem for storing secrets; but would like to only provide file information to certain users & processes.
However, I can't see how to get user & process info.
Looking at the code, we retrieve the information every time we're called, through get_thread_locals();
However, the user info etc. is discarded. Maybe we could put it into fuse_thread_locals_t, fill out the values, and then pass it with the calls somehow?
My NAPI is not strong enough to see an easy way...
