Might be a good idea for the CPS to have that case up their sleeve to advise the judge/bench for future cases. However, getting them to be consistent and effective has proved a rather difficult thing in the past, as many UK police officers will be able to confirm
The CAA recently added another offence which will make it easier to get a conviction for a lesser offence. Paraphrasing, it is now an offence to point a laser or light at an aircraft in a way that might dazzle the pilot. One of the perceived problems with the previous offence was that the prosecution needed to prove endangerment. That is no longer required with the new offence.
There is a degree of lack of joined-up thinking about this. I recently read in a UK sailing magazine about emergency flare replacements that are being sold. They consist of a high-powered laser (30 nm optical range) to be used to shine at SAR helicopters and lifeboats DUH! [The "need" for these has occurred after one or two sailors have been injured when flares have mis-fired]
