Yes, if they are power users like you and me who knows that removing
that file is safe. I think for most users one file is sufficient
because it reduces bandwidth usage (I'm on a metered internet
connection so larger files are more expensive) and disk space.

As someone who don't use MSYS I don't understand the advantage of
duplicating the files? You mentioned unzipping Emacs over an MSYS
installation, but that seems a little odd. Usually on Windows you
don't install software that way. But maybe for your use case you can
use the larger file? It includes a lot of
dependencies like Python2.7, Sqlite 3.20, and OpenGL headers which I
don't understand what they are doing.

For sure. :) But I like to waste time optimizing software so perhaps
I'm more sensitive than most. Hot start of Emacs 24.5.1 takes almost
exactly 7 seconds and of 26.1 8 seconds. I do not know how much of the
slowdown is caused by the larger executable, but I bet at least some
of it is (I will have to check after I have installed the right
version of MinGW and the right version of strip.exe). If Windows is
doing stuff in the background (like disk indexing or whatever its
services are doing) the load times increases further.

Will do!
