Yes, they matter in some cases. Often more in terms of safety than

A month or two ago I happened to plug a piece of equipment in which some
dolt (technical term) had connected neutral to ground into an extension
cord that some other dolt had wired with a hot-neutral swap. The results
were nothing short of spectacular on a high current laboratory circuit.
If I knew the identity of either dolt, I think I would teach them the
difference between hot, neutral and ground in a way they wouldn't soon forget.
