I think you're being rough, but then again, I've seen a couple of decoder boards where the soldering seemed somewhat suspect. Of course, some of my soldering is suspect as well, but in any case, the wires are 'delicate' (24-28 ga?).
I tend to cringe myself when I'm ham-handing decoders into place, which is why I like the ones that have a harness/plug combo.
