I have always thought Ederson was average (at least as an elite GK) in shotstopping, but still the best (obviously behind Neuer but he was untouchable) possible GK for our side. But football evolves. And Ederson has barely improved(I actually think he hasn't improved at all since he came to City).
GK's average passing ability now is 10 times better than 2017, and now I am not so sure if the superiority of Ederson's ability with the ball are enough to his shortcomings as a shot-stopper. In 2017 he was 3 times better than average GK with his feet so him not being great saving goals was not a big deal. He still is the best with his feet, but the distances between an average GK and Ederson are getting smaller and smaller. Cortouis for example is an average elite GK with his feet, and I think he would be fine doing 85-90% of Ederson's passes, and his shot-stopping abilities are far superior. We just saw Ortega in Camp Nou against a high-pressing team, and he was able to pass the ball almost as effortless as Ederson, and that shows you how much GK have evolved in the last 5 years. Sure no one will ever have the power that Ederson has in his feet, but how many times in a season does he need to use that? Once, twice?
People try to go to extremes and imply that all other GK are like De Gea with his feet, when every other young GK is pretty good with the ball. I think other positions have a bigger priority than replacing Ederson, but I am pretty certain that soon we can get a much better shot-stopper that still adapts really well to Pep's idea.
