Modulo any possible bike-shedding of the patch 14 helper flag
names and values, I think the entire patch set is ready.

The mechanical nature of the target helper changes means that
any bugs in the flags are still present, and you have not
added any more.  A timeout waiting for target maintainer acks
would be appropriate, I think.
