email fellowship programs if participating in ERAS??

AAMC/ERAS mention multiple times that an applicant should contact ALL programs to make sure they are participating in ERAS for the application year. Does anyone actually do this??? If the fellowship program website says requirements include "ERAS application"... that means they are participating in ERAS, no? And will programs really be forthcoming if you ask whether they are taking an in-house applicant?
