The thing is Heroku is not a library, it's a platform that allows to deploy web applications painlessly with only "git commit". Infrastructure is more than just libraries, and that's where other Lisps lack severely.
Common Lisp, for example, has only recently got a centralized library repository with dependency management (Quicklisp) but it's still in beta and not as robust as it can be (a library needs to be added manually by the Quicklisp maintainer to get into the repository). There is nothing like that for Scheme that works across all implementations, only a bunch of incompatible NIH solutions with only Chicken Eggs having a solid amount of frequently updated libraries (PLT Planet, the next biggest repository, is really poor in comparison). And that's only the very basic things, but because they are in a such rough state there's no way to have something more advanced like Heroku. You can't move forward when a solid ground is absent.
And you you won't move with this attitude of calling everything practical ``hipster shit". This attitude is the key, it's not even about a size of community, because Haskell devs managed to create a decent and steadily growing Hackage, regularly release Haskell platforms, etc. There is a bitter irony that Lispers here just
love to call Haskell a dead
dog.
