It does force a requirement for instrument ratings in IMC (which I think is currently true anyway since the end of the IMCR?) and it forces pilots to get an ATC clearance to fly into cloud, which I think is entirely sensible and safe.
I'm glad you think it's sensible and safe. But let's look at the real life risk for a moment. Could you point me at the last mid-air collision in the UK that occurred in cloud please?
