Hello, I finally figured it out:

It is not, it was in the documentation the whole time. The effective
handler is the outmost handler, unless #:unwind? is #t. I was tricked
by the obscure scheme jargon, but this works as expected:
(with-exception-handler
(lambda (exn)
(catch #t
(lambda () (error "to be caught"))
(lambda e (pk 'caught! e))))
(lambda () (error "oops"))
#:unwind? #t)
