I thought that might be the case. Out of curiosity, have you compared to treating everything implicitly and using a relaxation split so that preconditioning of the slow physics (maybe with Jacobi) didn't interfere with the treatment for the stiff physics? Also note that "burying the explicit integrator in function evaluation" (do you have a shorter name for this?) may not be performant with a many stage integrator since the cost of the explicit integrator is essentially quadratic in the number of stages.
