I think you are right Corwin with respect to native compilation. Eli's
opinion is that we don't have to pack the dependencies for Windows.
Please see the thread:

  https://lists.gnu.org/archive/html/emacs-devel/2022-01/msg01020.html

For other "convenience dependencies" he advised me to look at
nt/INSTALL.W64.  Here's the list of packages for features which,
ideally, should be available in a GNU-Emacs distro out of the box on
Windows:

  mingw-w64-x86_64-xpm-nox \
  mingw-w64-x86_64-libtiff \
  mingw-w64-x86_64-giflib \
  mingw-w64-x86_64-libpng \
  mingw-w64-x86_64-libjpeg-turbo \
  mingw-w64-x86_64-librsvg \
  mingw-w64-x86_64-lcms2 \
  
  mingw-w64-x86_64-jansson \
  
  mingw-w64-x86_64-libxml2 \
  
  mingw-w64-x86_64-gnutls \
  
  mingw-w64-x86_64-zlib \
  
  mingw-w64-x86_64-harfbuzz

So I'm more in line with Arash: Image-, XML-, TLS-, json-,
(un-)archiving- and some text shaping support should be available.

Yes, thank you Arash for pointing this out.  (Did a quick check, TLS is
not working, PNG viewing and EWW is not connecting to https sites.)

Currently we have 19 DLLs in the /bin folder (28.0.91), whereas 27.2 has
77 DLLs!  Corwin could you please check your build configuration, maybe
together with Phil?  (I'm sorry, I'm still of no help here.)
