I have to say, I find a similar experience.I think that's an interesting observation and experience. I could certainly see how the relative ease of saving characters from death could lead to a bit of laxness as well as the reputation of 5e as "easy mode" leading to overconfidence and then overextension into vulnerability.
In my experience, death is pretty uncommon (the PCs are 11th level in the game I'm running) but there's also a substantial difference between 3e/PF play and 5e. With magic items being "special" again, there are a lot less self-tailored/purchased utility items like wands or scrolls of flying. And as a result, the group is relatively low on oddball utility magics that tend to make obstacles in dungeons too easy. They're back to more creative uses of what they have like in 1e/2e days. And that, to me, feels ideal.
A Ring of Jumping has probably seen the most consistent use in my current campaign. The player picked it up, more or less on the, "Well, no one else wants this, so I'll take it" line of thinking and it's since become a really signature item. The bard's Wand of Illusions has also become a real go to thing. OTOH, the magic items the Artificer has made have been mostly completely background stuff - an AC bonus here, and a magic crossbow. Sure, she uses the magic crossbow a lot, but, it's like a +1 sword - it's there, we use it, but, it's not really adding anything to make the game more interesting.
That's phrased poorly, but, I hope my meaning is clear.
