I think it's tricky, because if Typescript _didn't_ show up with tsc, then they would have had their fate bound to Webpack or something like that. And of course tsc and the language server go hand in hand. It's hard to understate the positive effects of tsc existing across the entire ecosystem!
I suppose in a way I'm complaining about a (mostly) non-issue, since bundlers all have good typescript support at this point.
