It has a lot to do with fatigue(I know I bring this up a lot). Just mechanically, it has a lot going on. Not only is activating almost every muscle in your back, it also activates your forearms(grip strength), hamstrings, glutes, quads, and depending on the rep range or weight it can also be cardiovascular draining.

Only other lifts I can think of as more body fatiguing is power clean, and continental clean because those also activate your arms and delts more, as well as basically everything else a deadlift does.

I've been slowly working on a new routine for my upcoming bulk to get more sets in for every muscle group as well as hitting legs and deadlifts twice a week. My thinking is if my first bulk day is leg day, I can mostly focus on my glutes and hamstrings, I can finish off the day with deadlifts just focusing on lower weight and form, and then later in the week I can start on a deadlift solely focusing on strength lifts, and theoretically it should give me enough rest time in between so it's not too overall fatiguing.

Deadlifts suck because most people say you should really only do them once a week. Which is honestly fine advice, but the improvement will be slower, and even with all that rest, you can still have a super shitty deadlift day.
