Yes and no...they no longer actively/formally make guests line up pre-park opening for an RSR FP, but a line will still form (the CMs just don't patrol it as much anymore). I don't think it's on the same scale as when the attraction first opened, but it's still the most popular FP in the parks. In most cases, FP are lasting until 90 minutes or so after the park opens. They were lasting over two hours prior to the Soarin' refurbishment, so once Soarin' re-opens, the demand for RSR FPs might decline again.
Unless you want an early return time, I would probably go do a ride or two, let the first rush clear out and then go get the RSR FPs. My family often gets there at rope drop (non-EMH morning), heads straight to TSMM and then go back and get the RSR FP.
