(I would dearly love to get rid of this ugly vmop thing everywhere it
lives. Such blatant overstepping of bounds! But that's irrelevant to
your patch, so ignore my rant...)

Maybe call this "startPaused" or something like that to indicate what it
does rather than who uses it (I first said to myself "startStopped", but
that didn't really work well :-)
Or if you wanted to make it more complicated, you could have an
"extraArgs" arg instead; but I guess we shouldn't bother with anything
like that until/unless we have more than one arg that we need to be
optional.
So, pending a rename to something that indicates what it does rather
than what it will be used for, ACK.
