postcli -throttle?

[kcsf]

I got really excited when I saw this option, but it appears to be an invalid flag.
Is "throttle" implemented in any way in postcli?

`type InitOpts struct {
DataDir string
NumUnits uint32
MaxFileSize uint64
ProviderID *uint32
Throttle bool
Scrypt ScryptParams
// ComputeBatchSize must be greater than 0
ComputeBatchSize uint64

// Index of the first file to init (inclusive)
FromFileIdx int
// Index of the last file to init (inclusive). Will init to the end of declared space if not provided.
ToFileIdx *int

}`
