Wildlife will despawn eventually, yes; but they respawn eventually to.

Loot is different in the current version of PC compared to the version on consoles. If I'm right, on the consoles it's still the case that every zombie corpse is lootable, but may or may not contain things? These looted zombie corpses were typically empty, with about 10% actualy having something, 5% of that being useless junk, 4% of which were things of dubious use, and 1% things of actual use.

Well on PC it was changed so that zombies have like, a 4% chance to drop a yellow loot bag which is guaranteed to have some things of use in it.

So, if I'm right, then, technically, yes, the drop rate lowered from 100% to 4%, but, overall, you'll get more useful things out of it without spending half of your game day checking empty corpses. Just listen for the chime indicating a bag dropped and you can get on with your day otherwise.
