A simple poll would be the answer, guys. Though you-know-who might be the only one to vote for level scaling.
Realistically speaking, I think level scaling is a mechanic that you'd have to have had in mind relatively early in the development process to then start building your game accordingly. I imagine the difference in gameplay between using such a system and going unscaled would have to be catastrophically enormous, and I don't think that even Gyson would desire such a thing at this point in the game's development as it would be at best hasty and delivered at a low quality unless massive delays (many many months) are set to rework the entire game to accommodate the system were it to be implemented, and would certainly knock it back right out of beta into potentially pre-alpha for bug testing all over again. Though I think the merits of a system would be more appropriately discussed in any future endeavors beyond OS that Larian or other RPGs of this type decide to take on at the early or pre-development cycle.
Right now all this is is rhetoric being traded back and forth. I do not expect Larian to implement any relevant changes concerning level scaling in OS right now, but it might give them an idea of how to approach it in future projects like this.
