Are there ever any plans to do so?
(this question also goes out to every other vendor that is shipping an LTO
toolchain or plans to. Chad?)

I'm just trying to figure out how much of a Sony-specific issue this is.
Our customers are very performance-hungry and so we would like to provide
the option to middleware vendors (e.g. a physics library). If there is a
strong general desire in the community to not support this use case, we
will want to factor this into our internal decisions.
