Not must, as it's still voluntary/up to the rider, so far.I see nothing in it which suggests that. The start of that Tweet thread says "Our officers were busy on Tuesday conducting a number of road checks as part of the festive drink/drug drive campaign as well as educating a number of road users of the highway code"
The highway code says you should wear a helmet. So speaking to them on the matter of protective headgear is perfectly within the last part of that.
