"Namescope" is what I come up with when lacking caffeine. That bug
has been fixed in the meantime.

Yes. I mentioned it because newbies might follow the conversation.
As far as the style guide is concerned, I think it is useful to keep
the possibly differing semantics in mind:

(define (bla blubb) ; accept all bindings as they are now

(define bla         ; I need some original bindings here
  (let ((...)) 
    (lambda (blubb) ...)))

So, (define (bla blubb) ...) is my default. I agree with all the
reasons you gave.

NB: the Chicken compiler assumes standard bindings by default.
Hence, redefining * will work in csi, but it will not work, if
compiled without (declare (not standard-bindings *)).
