Combining these two quotes because I think they are related.
For me, the Morocco pavilion has always been the most unique of the World Showcase pavilions because it seemed the most "real" of any of them. The other 10, though especially the European pavilions, are all very clearly idealized representations of their countries with a lot of the edges smoothed out and different styles/architectures/regions/time periods melded together in a small space. As you say, the artificiality is part of the charm, and that's why things like stamped brick don't feel as jarring (though they should still try to make it look as real as possible).
That's not to say the Morocco pavilion isn't heavily idealized either, but I feel it's not quite to the same degree as the others. Some of that is probably because there is no such thing as a perfectly clean and orderly souk - the chaos and decay is part of the charm so you don't want to strip it all away. But there is a look, a "feel" to the area that's different from the other pavilions somehow. It's a subliminal thing you can't quite put your finger on.
And a lot of that, I think, is because Moroccan craftsmen had such a hand in it's construction. Now, if the King wants to send his artisans to Orlando to help build the thing, who is Disney to refuse (I certainly wouldn't!). But with that came an added dose of authenticity that I think should be celebrated and enhanced, and I think it's a shame to move away from that, even if in a very small way by faking tiles for a restaurant sign. I mean, Zach even made it a point that they added an "authentic mosaic fountain," so why go for the same authenticity for the sign?
Anyway, I'm willing to agree to disagree on this going forward if you are, though it's been fun having the back and forth.
