Finding icing conditions to show someone what ice on the wings looks like is like cutting the fuel to the engine to show them how to deal with an engine failure.
A tad dramatic
A better analogy may have been the EFATO in a twin drill:
Dangerous yes.
Should be practiced yes.
On an ISA day, the freezing level is likely to be about 7-8000' AMSL, and progressively warmer as you get lower...
Except for certain areas of the UK, 7-8000' AMSL is quite high and
well above MSA.
A thin layer of stratus, at those levels, will give you a taste of light icing, which a descent of a couple of thousand feet will rapidly clear** (** assuming you notice it accumulating and don't leave it until it is thickening)
IMO it makes sense to train for this eventuality just as much as training for any other emergency situation.
A badly handled PFL is just as dangerous (more so??) than light icing at altitude when you know the temp/MSA below you.
