Fyi, I found one project looking into a rdline pointer to get the back
reference to cmdline stored in opaque.
https://github.com/Gandi/packet-journey/blob/master/app/cmdline.c#L1398

This cmdline pointer is then dereferenced to get s_out.
Given that we announced cmdline becoming opaque, they would have to
handle the first API change in any case.
I don't think another API change would really make a big difference to them.

Plus, this project seems stuck to 18.08 support.
