Hello,
Using the following Org file:
Paragraph zero...
#+begin_src scheme :tangle org-output.scm :noweb yes
(list <<my-list-item>>)
#+end_src
Paragraph one...
#+begin_src scheme :tangle no :noweb-ref my-list-item
(+ 1 2)
#+end_src
Paragraph two...
#+begin_src scheme :tangle no :noweb-ref my-list-item
(+ 3 4)
#+end_src
Paragraph three...
#+begin_src scheme :tangle no :noweb-ref my-list-item
(+ 5 6)
#+end_src
After calling `org-babel-tangle', the contents of 'org-output.scm' are:
(list (+ 1 2)
(list (+ 3 4)
(list (+ 5 6))
Notice how all lines start with '(list', while only the last line
contains the closing parentheses.
However, if I use the following noweb[1] file:
Paragraph zero...
<<file.scm>>=
(list <<my list item>>)
@
Paragraph one...
<<my list item>>=
(+ 1 2)
@
Paragraph two...
<<my list item>>=
(+ 3 4)
@
Paragraph three...
<<my list item>>=
(+ 5 6)
Which was created using the linked one-page guide[2], I get the
following (expected) output:
(list (+ 1 2)
(+ 3 4)
(+ 5 6))
This noweb output was generated using the following command, from
version 2.12:
notangle -Rfile.scm my-noweb-file.nw > noweb-output.scm
Although the current Org behavior can be useful in some situations, I
would like to know if it's intentional before using it, and, in that
case, if it's documented anywhere in the manual.
Thanks in advance.

Yes, it is intentional.
See https://orgmode.org/manual/Noweb-Reference-Syntax.html
Search for "prefix".
Also, see :noweb-prefix header argument.
