Telegram's optional int/bool/float fields are pointers so callers can explicitly send false or 0 to override a chat default — distinct from 'absent', which uses the chat default. The pointer construction has been ergonomically painful: photoLimit := int64(5) Limit: &photoLimit api.Ptr[T any](v T) *T collapses that to a single line: Limit: api.Ptr[int64](5) DisableNotification: api.Ptr(true) Pointers stay because the explicit-zero distinction matters for fields like DisableNotification, ProtectContent, and getUpdates.Offset where sending 0 / false explicitly is semantically different from omitting the field.
