I'm sure the matter is taken seriously, though you have to appreciate there has been a lot of work and improvements since the first signs of trouble. They have built an onshore testing site to evaluate the problem properly, and combined with information from deployments, the temperature issues and how this affects performance is well known. Operationally they understand well the point at which the power system will fail and have a workaround to avoid this happening. They simply bypass the intercooler-recuperator when the system gets to a certain temperature and the thing keeps running - without the efficiency benefit however. The last time there was a power system breakdown was many years ago.
There's a design and product procurement phase to get through before they can perform any implementation, as well as wait for an appropriate slot in the schedule - should be in 2020.
