It was just a comment about DIYing electrics in general. Reversed polarity, switching on the neutral rather than live conductors, high resistance joints, badly terminated connections, too much bare conductor exposed.
There’s loads of little things that could occur and pose danger while the lights still work.Switching off the circuit labelled as lighting is no guarantee of safety either without means of proving dead.
I’m definitely being pedantic. And I’ve got skin in the game (I’m obviously going to espouse the advantage of using a spark).

I know. This is true whether the circuit is earthed or not, I think? Although it's possibly more likely to install a fitting in a way that's less than acceptable with a circuit that has no earth. But class ii fittings exist - like the plastic ceiling rose - to side step the worst of that.
Yeah, it's unlikely. I was referring to tooling a consumer needs to verify the wiring they are working on is 'dead', having been shut off at the fuse box / consumer unit.
