[BUG] RFE: Including src-blocks from different files when tangling the code [9.5.5 (release_9.5.5 @ /usr/share/emacs/28.2/lisp/org/)]

[Garid Z.]

I have following Request for Enhancement: Write src-block in separate
org-file(s), and when time comes to tangle use all those src-blocks
using some sort of reference.

In other words, take a look at following an example:

--------------------------------------------------------------------

    * This is ~/tmp/1.org~ file:

    #+name: code_block_in_1_org
    #+begin_src python :noweb yes
    import pandas as pd
    #+end_src

--------------------------------------------------------------------

    #+INCLUDE: "/tmp/1.org"           

    * This is the ~/tmp/2.org~ file
    #+caption: Local Code Block
    #+name: code_block_local
    #+begin_src python :noweb yes
    import numpy as np
    #+end_src

    #+caption: The Final Code Block
    #+name: the_final_code_block
    #+begin_src python :results output :tangle output.py :noweb yes
    <<code_block_in_1_org>>      # referencing from 1.org
    <<code_block_local>>         # referencing from within 2.org
    #+end_src

--------------------------------------------------------------------

The file ~/tmp/1.org~ contain src-block (~code_block_in_1_org~)
which is needed in block (~the_final_code_block~) of ~/tmp/2.org~
to tangle:
 - When ~/tmp/2.org~ exported to PDF via LaTeX, ~the_final_code_block~
 does contain part of code from ~code_block_in_1_org~
 - When ~/tmp/2.org~ tangled, ~the_final_code_block~
 does NOT contain part of code from ~code_block_in_1_org~

For consistency with PDF-export and file(s) management reasons,
I feel like it would be neat/cool have this feature to
spread src-blocks to different org-files.

Please take this RFE with a grain of salt, since I'm not that well
skilled/experienced person. And, I'm not even sure this spreading
src-blocks all over the places/files will be beneficial to overall
literate programming paradigm. Just for my small case, it felt
beneficial.

Please share your opinions on this, I will be  happy hear about it.

Best,
Garid Zorigoo.
