Yep.

There are setups out there that have been using this for a very long
time, so I wouldn't call it experimental. I rarely, if ever, test with
this code path, truth be told. What we need to do is combine both
together; i.e. use the newest commands by default and fallback to the
old ones if any error is seen with the newest ones.
