What is the discoverability gain? I am curious about the separation of the old tag name into type and context. With the new one, I cannot search for all users with rank=90 anymore. I can only filter for w=rank on Nostr filters. The other ones are weird because the "value" context doesn't say which value. So, if my client displays zaps sent only via `zap_sats_sent`, I cannot filter only the events that include `zap_sats_sent`. I can only filter by w=value, which doesn't seem that helpful.
We could add `w=zap_sats_sent` directly to the old TA spec if needed so that we can filter by all users monitored by the `zap_sats_sent` provider of the user.
