I mean, you could use that argument for anything. "I don't know/care about X therefore no one cares about X."
Personally, I find his casting interesting for a number of reasons. One, him joining the roster makes Great Comet one of the few shows ever to have two non-white leads in a show that isn't explicitly about non-white people (ie. The Color Purple, Miss Saigon, etc). It's even more intriguing when you acknowledge the fact that the characters are two beloved Russian protagonists who are pretty much the archetype of white aristocracy.
Two, I think his poppy, youthful vibe will bring something very different to the character than Dave Malloy or Josh Groban's interpretations. Whether that will be a good or bad something is still anyone's guess, but it'll be exciting to get something different from the character.
Three, I mean. He's a replacement for the lead in a popular Broadway show. Even without points one or two people would still be talking about it.
