I usually dig a little hole with a claw hammer before driving in the lags.
This gets the lag a little deeper, an important part of the process as there is a "top layer" of playa that has no benefit to the lag or rebar's holding capacity. Sometimes this non-gripping playa can be 6 or more inches deep.
Unfortunately, once the hex head of the lag is below the surface, with only one or two chain links protruding, when take down happens and mule tape, rope, or ratchet straps are removed, it is VERY hard to see where all the lags are buried.
It would be wise when set up is finished to COUNT how many lags are being used, and make sure you have that many when you remove them.
As seen in day 3 of the journal of the restore team mooping up BRC:

This is Resto’s first encounter with the new technology in tent stakes. These have two links of chain attached for fastening, and they seem hardy as can be, plus easy to install with an impact wrench or impact driver. So then, maybe the owners of the dozen or so of these things left behind thought they weren’t so easy to uninstall. But even if your impact-driver-owning campmate has gone already, you CAN pull these out with vise grips. TL;DR mind all your tent stakes and keep a vise grip in camp.
