Is this really necessary? What parts of the OpenSSH need patching, and why
disabling Kerberos support?

Noted. Though, it took several attempts to find links to a source code on your
And "Download binary" links dumping visitor into a directory full of
different versions isn't speaking to your advantage.
Take example from and rework your downloads page.

I have a counter-question. Any objection you have to distribute your
application as part of Cygwin infrastructure?
You can still keep your NSIS installer, assuming you change it to download
appropriate setup.exe, and you could offer an option to make portable
installation from live system, knowing well that it's already rebased and
ready to work.
And Cygwin users, who also happened to be users of your app, will benefit from
NOT having to solve conflicts between multiple Cygwin1 DLL's.
