PowerPoint I believe you (or at least don’t know enough myself to argue). But for Slides, there’s no way. How, for example, would you put an outline around text?
Or embedded videos, or non-trivial animations, or non-Google fonts, or transparent strokes, or vector shapes (excluding the workaround I shared above). Sure, you can win clients without any of that stuff. Why do you need anything more than basic text and maybe some pictures?
But there are reasons people and companies strive for more polish and professionalism. There's a reason even Google uses Keynote for the I/O keynote, even though you can technically show the same information in Slides.
