I see what you're saying, but IMO beer is both a bad example AND similar to coffee in many ways.

It's a bad example in the sense that the flavors you get out of fruited beers tends not to be as 'funky' as in coffees because fermentation is controlled so closely. You can get some incredible flavors out of adding adjuncts to beers. Yes it's interesting and cool that you can get some of those flavors out of yeast, but there are also flavors you just can't get from yeast that can be delicious.

It's also similar to coffee in that adding extra things is not somehow new or novel, it's actually very old, we're just rediscovering it.
