Yes, it's better to have the reference in case we need to revisit this.

No, I mean before configured state, is the device considered
self-powered? Since being self-powered means drawing 100mA or less, we
can use USB_SELF_POWER_VBUS_MAX_DRAW to provide more context. If it's
totally unrelated, then you can ignore this.
