No, there will not be an improvement.  -Xclang is an internal interface
that has been exposed to users with a lot of explicit warnings and caveats.
It is much better for it to have a simple, consistent specification than for
it to accumulate features (and so ambiguities) in the interest of being
easier to use.  Anything that we actually want to be easy to use should
be exposed through a proper driver option instead.
