Sure. The kernel still continues to provide the trampoline for
binaries which do not provide their own. I was quite careful to
maintain compatibility.
I guess the point is that there are already "different paths" (which
really means "multiple small functions that convert the internal
representation to the external representation"), and I just don't see
the issue with continuing to provide the traditional sigcontext "path"
for binaries that do not request siginfo.
