Is CRA Development Program worth it

I recently got a promotion within my company but the job responsibilities have been quite the same. I found out that an IHCRA or CRA Development Program is currently available internally and this is something I had been interested in and would help with my career goal. I am stuck in this difficult dilemma on whether I should apply or not since I do not want to sound ungrateful or make my leader feel like I desperately want to leave my current role. Should I take the chance in applying and would it be worth it in the long run considering ihcra roles have been unstable lately?
