FIFO enforcement on Profile Ingestion

Currently, FIFO is not guaranteed when ingesting data to Profile, even if you have a timestamp available. This has been confirmed, both theoretically and practically, by external Adobe consultants. 

My feature request is to have the option to enforce FIFO upon profile ingestion. It could be a toggle, that would be off by default, when configuration Base connection and/or dataflows. 

It will, potentially, have processing time implication, but from my business standpoint, I would rather have correctly updated profiles, a bit slower, than fast updates that are potentially incorrect. 

This would be a massive product improvement in terms of functionality, personalization and data activation in general.
