A few questions about complication updates

This talk didn’t mention the transferCurrentComplicationUserInfo mechanism for updating complications. Is this just because it’s not relevant for standalone watch apps? Are you still planning to support this mechanism going forward?

Also, transferCurrentComplicationUserInfo and push updates are both limited to 50 updates per day. Are these separate limits?

Is Apple able to grant exceptions to these limits for certain applications?

Lastly, Apple supports some dynamic complications, such as the Noise complication. Are third party apps able to do similar things?
