... the result is that the rocks around the interstices will increase
significantly in temperature.


My understanding has been that the water is heated a great depth and then
carries the heat upward.  If that's true, the rocks close to the surface
(within the geysers plumbing region) will never get hotter than the water and
they won't heat without water moving through.

I don't have a reference, so speak up if you have contrary evidence.  Are the
rocks heated by the water, or the other way around?
