The decision to rename TEXINFO_DIR_TITLE to TEXINFO_DIR_NAME?

Actually, looking into its history it seems that that particular change
was made by Stefan Monnier in b0c3c90574ed79a63e56acaeee156ef8d9593233
in the org-mode repository.

I don't understand.  The generated Texinfo file will use the
TEXINFO_DIR_DESC keyword as the description if provided.  If not, it
uses the TITLE.  The TITLE and TEXINFO_DIR_DESC in m-buffer-doc.org are
currently identical.  I.e., the generated Texinfo file should be
identical even if TEXINFO_DIR_DESC were to be omitted in
m-buffer-doc.org.

I'm not stating that it should be, only that it could be without causing
any changes.  And the only reason I mentioned this is because of the
following comment in m-buffer-doc.org:

#+begin_src org
  # FIXME: Shouldn't `ox-texinfo` use sane defaults like the file's name
  #        for TEXINFO_DIR_TITLE and the TITLE for TEXINFO_DIR_DESC?
#+end_src

If omission of TEXINFO_DIR_DESC results in a variation in the generated
Texinfo file, then perhaps a bug should be opened against ox-texinfo.
