FWIW, I've got the main COFF functionality that I had planned on doing 
committed in trunk by now. So at least for my own usecases, it's fully 
functional by now. (And for unsupported options, it clearly errors out.)

If there's an interest in this, it should be easy to backport to the 
release branch (with no regression risk, as I believe none of the patches 
since the branch touch anything outside of the COFF directory), but I 
don't have a direct need myself to have it in the release.
