Has anybody considered the possibility that Chryst's excellent performance is in part due to the pressure he feels with Costello nipping at his heels.  That Shaw is manipulating the QB situation, including public comments and QB rotation, in such a way to motivate his personnel.

The above is a primary reason why rotating QB's is usually not a good idea.
As a person new to being a fan of Stanford football, my opinion is that Costello's outstanding performance against UCLA earned him the right to continue as Stanford's starting QB.
I think Chryst had many opportunities to perform during the Hogan era,  7 games last season following Burns injury, and this season in the starts against Rice, USC, SDSU, and the early part if the UCLA game. If Chryst play was not outstanding during those 10 starts then why not give Costello his opportunity now ?
