Add support for custom data connectors (Power Query M extensions)
Custom Data Connectors mechanism is being developed by Power BI Desktop team:
Excel's Get & Transform engine (Power Query) should have support for .mez/.pqx extensions too.
This would be very helpful, please implement. Or at least put it on the roadmap.

As I understand the video (around 51:30) they only say, that they have the same technology (Power Query) in Excel also. When they talk about custom connectors only Power BI is mentioned.
Interestingly, in this video (https://www.youtube.com/watch?v=3wjHBNfWteg) from the Power BI Team in June 2019, Microsoft said this is already available in Excel desktop (around 51:30). Although this GitHub issue (https://github.com/microsoft/DataConnectors/issues/82) from a month earlier Curt Hagenlocher said that the Excel team has no immediate plans to support it.
Just thinking about the possibilities gets me fired up. Please, oh, please!!!
