Every attorney will have a different advice. Mine advised me that it's best to let your passport expire and simply forget about it, and to use/renew RTD as needed until you get the citizenship. I am personally very okay with the "hassle" of having a RTD ever year, applying for visas to travel, and even being stopped by passport control on a RTD, if this means I am free from persecution, safe, and on the way to get my citizenship without being hostage of my passport and risking questioning/being stopped. It's a very short-term first-world problem in the grand scheme of asylum/citizenship things.
