Webhooks already exist for Clients, Contacts, and Time — extending them to the two resources everyone actually orchestrates around would be huge:

Project created / updated / deleted — especially tag changes, since automations drive them

Task created / updated / completed

Today the only way to notice a change is re-pulling the full project list on a timer (the list filters like updated_since aren't applied, so it's all-or-nothing). Webhooks would mean real-time integrations and less polling traffic hitting your servers — everybody wins. ⚡
