It already does:

  ** Download and install the necessary packages

  Run msys2_shell.bat in your MSYS2 directory and you will see a BASH window

  In the BASH prompt, use the following command to install the necessary
  packages (you can copy and paste it into the shell with Shift + Insert):

    pacman -S base-devel \
    mingw-w64-x86_64-toolchain \
    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-libxml2 \
    mingw-w64-x86_64-gnutls \

  The packages include the base developer tools (autoconf, automake, grep, make,
  etc.), the compiler toolchain (gcc, gdb, etc.), several image libraries, an
  XML library, the GnuTLS (transport layer security) library, and zlib for
  decompressing text.  Only the first three packages are required (base-devel,
  toolchain, xpm-nox); the rest are optional.  You can select only part of the
  libraries if you don't need them all.

ImageMagick is not listed because the Windows build doesn't support it
yet.  All the other packages are (or should be) listed; if you think
something is missing, or the text below the list is unclear about
what's optional, please point out what should be

It is not meant to be misleading, it is meant to list everything.  And
I think it does.

The above is that complete list.

I don't know.  I suggest to ask the author.
