Let's not get carried away too far in this discussion. The key point is to help GA pilots and GA organisations to get the Notams which are important to them and their flight easily and quickly and to avoid dilution by Notams not relevant.
In this context, GA flights are numerically far larger than the airlines, including not only private pilots flying for fun and business, but also air taxi, medevac, training and small corporate outfits etc, none of whom have the resources of a comprehensive ops department for pre-flight planning.
If a specific Q-code is irrelevant, it should be possible to filter it out individually, or as part of a family. I subscribe to Pilotbrief, who provide this facility and it works well -- but you do have to subscribe. So, it can be done. AIS should provide the raw data, allowing the users (or commercial intermediaries) to provide the filters.
For filters to work well, the timing, radius of action and altitude limits of the issue need to be well specified. This is an area where AIS could intervene to sharpen up the data quality from the original source, and promulgate refined data in the UK.
