The reality is that for most of Corporate America banning PowerPoint is not going to happen anytime soon. In our industry, decks are viewed not just as presentations but general fodder for deliverables, handouts, etc. I've been on several engagements where we intentionally jam-packed slides full of content (including multiple levels of footnotes) so they "stood on their own" in case someone picked up or distributed the deck after the meeting in which it was used.
If I was giving a talk I'd agree that presentation style would be overkill, but I've been in meetings with C-level execs and VPs where the extra info has paid off by being able to preempt questions and provide additional justification for the conclusion. Sometimes having a crowded slide is more "professional" in a meeting context than alt-tabbing to the detailed Excel worksheet showing the assumptions.
