This triggered an "er, shouldn't we be using the SRK parent by
default?" search through the code, but it turns out that's all taken
care of in trusted_options_alloc() where we'll set up the SRK as parent
with well known auth and unless overridden on the command line, that's
what we use, so I'm happy this is simply left over code from a
different implementation of that use case.
