I am sure this is a huge relief to the Blue Origin folks to have these issues if not fixed, at least understood so that they can be fixed and the engine put into production.
Slightly more powerful than the SpaceX Raptor (550 lbf for the BE-4 vs 500 lbf Raptor) both engines are designed for re-use. As the BE-4 gets closer to production, and the Raptor gets some flight tests under its belt, a clearer picture on the thrust to weight and dynamic range of throttling will become better understood.
But the really awesome thing is three orbital class re-usable engines available from US vendors for the first time ever. This bodes well for the US space industry. Not so good for Aerojet/Rocketdyne which, in my opinion, has basically rested on its laurels as the "only game in town" for US built engines for far too long.
