@Max,
@sam.mckay does an excellent job breaking down the problems with quick/implicit measures in this video, though he is slightly more charitable toward them that I would be:
Not as bad as the auto-detect relationships feature (IMO the absolute worst idea incorporated into Power BI) or the auto-time intelligence (@Heather’s vote for Power BI supervillain), but a strong bronze medalist.
If you watch the Guy In A Cube videos, Patrick LeBlanc dislikes quick measures so much that he actually wrote a custom tool to link into the new External Tools menu to turn off all the quick measure aggregations (and he works for Microsoft!).
