Yes I did notice.
The CAA are clearly concerned that it is far too complicated because they have already published two guides (
https://airspacesafety.com/updates/ ) to remind GA pilots of the rules under the heading,
"Preventing airspace infringements in the vicinity of Farnborough Controlled Airspace. This infringement update is intended to follow the format of the narratives focusing on identified infringement ‘hot-spots’ in the UK. It has been written to provide pilots with a comprehensive guide to the Class D and Class E Farnborough controlled airspace which become effective on 27 February 2020 to assist in the prevention of airspace infringements."
