I try not to give out those items (ever) in 5e after noticing the same. I think the 2014 neovancian style of spell prep exacerbates the issue badly. A caster doesn't need a wand or whatever limited charge item to devote exactly as few or as many of a given spell slot level to x spell & they can usually even upcast if they need more.Again this is a real issue. A staff of fire or wand of lightning bolt each takes a single attunement slot but can change how many “not damage but I win” spells the wizard can use
The need for a wand or whatever of x spell created a concern about going crazy with it because it wouldn't recharge and finding a replacement might be hard to impossible. Having to prep each slot meant a caster always needed to weigh the cost/benefit of casting a given spell against the risk of potentially needing it more but not having it available later. All of that is gone now & it's just all "I Put on My Robe and Wizard Hat" dialed to 11 all the time .
