Not a stick maker but I do have to bend extreme recurves into wood often.
In my experience if you heat any green wood using steam or dry heat you run the risk of it splitting and checking. This is because heat of any kind steam or dry will remove moisture from the wood. This in turn causes rapid shrinking of of wood and internal/external fractures.
Given all of the above I still mostly speed dry wood indoors but I try to do it gradually, in stages and keep an eye on the RH.
For a guideline I steam for about 45 minutes per inch of thickness to be sure.
