Whether a notification with this JSON-RPC method (and, for
notifications/resources/updated, this resource uri) is one this stream
explicitly requested. An inactive filter (a plain GET stream) accepts every
notification; an active filter accepts only its opted-in types. Notification
methods that are not subscription-gated (progress, logging, elicitation
completion, server->client requests, etc.) are always accepted — the draft
filter governs only the four list/subscription change types.
