I would imagine that they would never launch 6E as the "less violence" edition, but instead offer products going forward to allow options other than kill the problem to solve it. I think the key, though, is "more options and approaches to customize your game" and not "we're changing how D&D works, and now you have to play it this way."
Let's face it, combat is fun - in RPGs, that is. It is central to D&D and has always been so. Furthermore, fantasy isn't reality. We role-play to experience things that we wouldn't normally experience (hopefully not!). We want to play mighty thewed heroes, powerful wizards, crafty rogues, etc.
On the other hand, we're deluged with stories via Hollywood (see "MCU") in which heroes mostly solve problems through violence. This has a propagandizing effect, I would say. It would be nice to see more depictions of heroes finding other ways to solve problems and defeat enemies, even recognizing that the "enemy" isn't necessary that. But, I think, there will always be a place--probably a central place--for wading into battle, crushing your enemies and seeing them driven before you. But it doesn't have to be the only way.
