Yes they are fucking up a fairly good system. It should be done as part of the building regulations so new properties / properties being renovated going forward need xyz or they could even add that if your adding an extension you must upgrade the fire alarm system.
Ripping out hard wired linked alarms in favour of radio linked is just nuts absolutely nuts. I worry that some radio link will fail because of interference and some poor family will end up toast.
It's a knee jerk reaction to Grenfell without considering what all went wrong. It was a concrete building fire should have been contained within the apartment it should never have been able to rip up the outside.
Smoke alarms wouldn't have made any difference, people in the building were being told to sit tight.
Honestly ScotGov are absolute muppets, and love people to think they are cuddly and caring but really they just screw thing up.
