But does this mean the good of the system should be discarded?

No, such absolutist thinking has no place.
The system of an exponentionally increasing difficulty doesn't mix well with a system where your power gain is capped.
It simply means that you'll reach a hardcap on what you can manage which is not really that enticing.
It somewhat works on D3 (graeter rifts are the blueprint of mythic+) but even there there's an hardcap on what you can do and they constantly have to power creep the game to allow ppl to go further.
