This is a stupid reply, if CoH1 did something right why are you discarding it? just because its CoH1?
You'll notice his comment isn't talking solely about this issue, but rather about how more mechanics should be like Coh1. For example, CoH2's original vp bleed for example made for a much better game, but it was changed solely because people wanted it to be like CoH1 so they could play their 45-60 minute 4v4 matches. The forums were chock full of "Waah it's not vCoH" sentiment ever since release. The game has been slowed down tremendously since it came out to cater to this mentality.
Moreover, I don't agree in this specific case. If you plant mines a lot, you also have a pretty good idea of where your opponent is going to be planting his mines. Should have 1-2 sweepers roaming around the map if you know your opponent is putting them down. If you're losing high vet squads to mines, you fucked up. You can also not take the most obvious and direct path everywhere.
I've only ever seen pgrens/sturmpios consistently get completely wiped by them due to their formation being a bit too tight. Everyone else survives with atleast one member left.
