I'd totally agree with that. If there's one exercise in the gym that's full of "functional" carryover to the real world, it's probably the deadlift or some variation of it.
This is why I was confused by the "golden rule" the OP mentioned. If we're talking about low weight, that's a different situation since the risk is clearly reduced, but a hard and heavyish set of 8-12 (or more) deads can certainly be a regular option for a non-beginner. Just ask Wendler and pretty much anyone who's done 5/3/1.
