I'm also in the camp that thickness above factory is irrelevant- PROVIDED the lug is properly bedded.
If the lug is bedded, and perfectly square to the receiver face there's no way it can flex at the receiver juncture.
Factory stamped lugs will never be perfectly flat. Absent a surface grinder, spend the $30-$40 for a precision ground lug when rebarreling. It's not about the added thickness- it's all about being perfectly flat and thus square to the receiver face. This results in recoil forces being "straight back", and not trying to twist the receiver up, down, or to the side as could happen with a stamped lug that's not making full contact. For most factory rifles, just bedding the lug will usually improve consistency.
JMO. YMMV.
