It would be a bit hard for Clojure to achieve that level of support.
They are trying to be the next Borland with Kotlin as their Turbo Pascal (#KotlinEverywhere), and got Google Android's team as the language godfather.
Because what I heard is that Google pay JetBrains nothing. They forked IntelliJ Community Edition to make Android Studio and have their own development team, which honestly sounds much more like Google to me.
VSCode just filled the void they left wide open. But I suspect Sublime and Atom are the main victims of VSCode.
OTOH Google at least doesn't try to kill them outright, just to assimilate them and headhunt their employees, but Microsoft would be happy if they disappeared instantly as many of their clients have an unwanted dependency on Resharper.
Most of GraalVM improvements regarding Scala have been thanks to Twitter.
I'm not saying that having more mainstream tooling wouldn't be good, but people should not be discouraged from Clojure or Lisp development because of an apparent lack of tooling.
And that's probably the only book that recommends setting up Emacs. It was published in 2015. Back then maybe the argument about tooling made sense, but honestly, have you looked around lately?
Every major editor today can be set up for Clojure programming.
Even most popular (and oldest) languages can't brag about being equally supported in all major editors, and Clojure can.
