Even if you just build an engine on-par with everybody else. Or even just a bit sub-par. Not everybody wants or able or have use case for those large top of the line very efficient and very expensive engines from the top manufacturers.

There are just too few of those engine manufacturers, even if sub-par, around for the current world demand. Anybody wanna make a startup for the engines, initially for UAS market? It is going to blow up after the war as drones have been showing their future dominance. And just look at that beauty (uses the Motor-Sich engines as Turkey don't have their own) https://en.wikipedia.org/wiki/Baykar_Bayraktar_Ak%C4%B1nc%C4... .
