If EDE finds this useful, what doubt is there that other Lisp programs
will?  How many examples do we need before we decide that a specific
trait of a project is "useful"?  I say one is enough (sometimes more
than enough).

That's exactly my problem: I find such an approach surprising, to say
the least, when building such basic infrastructure.  When you build
infrastructure, you don't wait for clients to come requesting basic
features.  You are supposed to study the use cases and the entities
you want to support, and provide support for at least the
standard/basic aspects and traits of those entities.  I think there
should be small doubt that access to project documentation, including
its build command, is one of these basics, because every project has
