That is a good point. I guess my initial thought is that it is a hard break, like lvl 20 in 5e. If you go past this point you are saying this the type of game you want to play. Otherwise, stay level 1-10. The game is full featured in levels 1-10 (in 5e terms take everything in 1-20 and mush it down to 1-10).I think the issue people find with your idea is that it limits heroes to those that are not mundane. Someone referred to it as ‘baby Hercules’. Because if a hero can progress in martial prowess past that mundane point then they never really were mundane to begin with and/or some supernatural power granting event had to occur right at level up (which is also a problem for people)
I think if you do the level split explanation you have to take great care to explain how these issues can be avoided if desired. (Essentially campaign level cap or starting point and why you would want to use those).
That may not satisfy everyone, but I am not looking to satisfy everyone.
