A more important aspect of 'usefulness' is the available ecosystem. Experimental
and toy compilers can be useful for individuals, perhaps (very) small teams. This
stops when you have to run a business responsibly, including documentation,
production, maintenance and what you have.

OTOH a good DSL built within and managed by the existing ecosystem can give you
a competitive edge.
