Not without adding hooks everywhere for passing them, no.

I felt the same, but the it is activated and deactivated right before
and after the actual loader call, so it can't get in the way of anything
else.  If it ever does, you can use the commandline option, and in those
cases, we can work out how to do it.  I didn't feel it was worth it to
start breaking API's just for getting this feature in.
