"Resin only" rotors

Bought a brand new 2017 Genesis Croix De Fer from a reputable dealer a few months back.
I commute in all weathers on a pretty hilly route (20 miles per day), with lots of stopping. I'm at close to 1000 miles and decided to give the brakes a good checking over this evening to see if there's much wear. The front pads do look close-ish (probably a bit of life in them yet, though). The rears don't look too bad.
Anyway, I'm digressing. What I did notice is that the rotors are Shimano SM-RT54 and they have "Resin Pad Only" printed on them. However, the pads (original, supplied with the bike when purchased) are Shimano J04C metal pads. I called the dealer and the guy I spoke to didn't miss a beat before saying it was nothing to worry about, and that metal pads are fine on the resin only rotors.
Reading up online this evening, there seems to be lots of different opinions on this matter. What do people on here think? And isn't it a bit strange that Genesis would have supplied the bike with mismatching parts like this?!

I've used a variety of pads over the years, in all sorts of conditions,and never worn out a 'resin only' rotor.
I agree with the dealer.I don't do smileys.

As CD, I've used lots of pads on 'resin only' discs, never had a problem, in theory they may wear out faster (that's the reason for the label, they are a 'softer' metal) but I certainly couldn't see I was having an issue.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0
