This is a very problematic view from a Windows system management perspective.

I respectfully (and strongly) disagree, for at least the following reasons:

* Cygwin runs on Windows, and as such should respect Windows security.
It is very unexpected, from a Windows administration perspective, to
have a disabled account and still be able to log onto it.

* Proper system management/security mitigation is made quite complex
with this requirement. Imagine even a small Windows domain: I have to
scan 20000 machines in my domain to find out if they're running ssh,
troll through the disks to find ssh config files, find out the key
file names, rename them, etc. This is quite a bit harder to do than
just disabling accounts, which in many organizations is handled by an
automated process.
