Older D&D editions specifically made combat much deadlier and incentivized players to avoid combat or use out-of-combat advantages as much as possible for this reason. Modern D&D caters to a crowd that enjoys metagaming and minmaxing combat more.

That’s not really true, IMO; older D&D made combat harder to calibrate to the desired level of deadliness because there were more irresistible forces and unmovable objects. Modern D&D is much easier to tune to the precise preferred deadliness. That’s pretty much a monotonic progression across the history of D&D. (Ignoring the boxed set series and considering just OD&D -> AD&D1 -> AD&D2 D&D/3/3.5/4/5, and leaving out the in-playtest One because I haven’t really checked any of the material out.)

IME and IMO, 4e was a local peak of that, but not more than either AD&D1 or AD&D2, especially the late era of the latter. Heck, in AD&D1 its was common for people who didn’t want the game to be dominated by the metagame to slice out big chunks that were oriented toward that (most notoriously, the weapon to-hit vs. armor class type system).
