Well, we shall see -- I have put in a comment.

No, I don't. I put in all the files that are declared as part of the
dependency package.

I could detect and remove specific dependencies, or with a bit more
work, remove a part of the dependency tree. But I rather not go down the
path of maintaining a metadata list for msys2 independtly.

So far, I have had no bug reports about this, just the opposite -- that
too much is included. And some requests to add other things. I'm just
not convinced that effectively producing a seperate minimal MSYS2
distribution is where I want to go. For people who want a lot more or
less, installing msys2 independently and then droppping the no-deps
package on top seems the way to go.

Hmmm. Sort of. If you click runemacs.exe from the windows explorer it
works. If you launch it from a mingw64 shell, no, it doesn't. Or rather
it works, but you get the msys info which doesn't link to Emacs.

I am rather dependent here on people filling bugs; I don't actually use
Emacs on windows, just build it.
