We do this to prevent foot guns. The default config uses a MemoryFilter, but users are free to change to logging to files directly. If they do then they have to ensure to set the `filters: [context]` on the right handler, otherwise records get written with the wrong context. Instead we move the logic to happen when we generate a record, which is when we *log* rather than *handle*. (It's possible to add filters to loggers in the config, however they don't apply to descendant loggers and so they have to be manually set on *every* logger used in the code base)
