The LHR CTR hasn’t been Class A airspace for quite a few years. It’s Class D.
Whether or not putting a restriction around Windsor (or anywhere else) keeps anyone safe is open to debate. Those wishing to do harm would obviously just ignore such rules.
Some, like myself might remember that Windsor did previously have a “red circle” around it quite a few years ago.
