The main thing to consider here is that 'they rarely fail' doesn't mean they won't fail. An older part is more likely to fail than a newer one.
I know Mick @ Diamond charges £110 extra for the dephaser according to his website, in my opinion while your already spending £470 on the cambelt etc you might as well get the dephaser done for peace of mind.
Mine is in the garage as we speak and I've gone for the full cambelt kit, aux belt, water pump and dephaser. I will definitely leave the garage feeling better knowing the full lot has been done - albeit slightly more out of pocket.
dephasers are a lot more reliable on the 197/200 unlike the 172/182 - never had mine changed to be honest but what is supposed to be changed is the crank pulley - renault did have issues with then splitting apart & did issue a service bullitin to have them replaced when belts done...once every 5 yrs so an extra £200 on top of the belt change..where do you stop?
I did mine with my cambelt just for peace of mind. You only pay for the part so may as well. Did the waterpump too... so I guess that’s where I stop!

mine just went in last night (its a 197 but yea) I decided to get the dephaser done as I didn't know what the previous owner did with the dephaser. I also got a lightweight crank pulley and water pump and the lot while its being done.
My guess is the perceived impact on sales that the maintenance schedule had. Nothing is actually different except the guidance. You're right the intervals are shorter. Probably the guidance for the 197 is better, but that said when I bought my 10 year old 200 with 32k on, it had the original belt and when it came off it could easily have been confused with the new one bar a bit of faded print.

But the 200 is newer, so surely that guidance is more accurate, as the belts are the same, the engine etc.
I can totally understand the time interval in your example, as it will perish over time.
So which is right? Haha, so confusing!

I did the belt and pump on mine this week. week decided to be guinea pig and not replace the dephaser.
Cars on 88k on the original one. Will see how long it lasts

it fits on the end of the inlet camshaft (uses oil pressure in a 2 piece housing cam pulley) and alters the timing between the cam & crank - advances or retards the camshaft/inlet valve timing relative to the crank....for better emissions at low revs & top end power
I was told once that the dephaser was revised later in it's life hence the longer intervals on 200 not sure if that's true or not.
