I tried make minimal cygwin environment where only sshd works.

With /etc/nsswitch.conf having the following two lines:

db_home /cygdrive/c/Users/%U
de_shell /cygdrive/c/Windows/system32/cmd.exe

, only the following files are necessary after running
ssh-host-config.

.:
bin/
dev/
etc/
lib/
sbin/
tmp/
usr/
var/

./bin:
cygcom_err-2.dll*
cygcrypt-2.dll*
cygcrypto-1.1.dll*
cyggcc_s-seh-1.dll*
cyggssapi_krb5-2.dll*
cygiconv-2.dll*
cygintl-8.dll*
cygk5crypto-3.dll*
cygkrb5-3.dll*
cygkrb5support-0.dll*
cygrunsrv.exe*
cygwin1.dll*
cygz.dll*
ssh.exe*

./etc:
fstab
nsswitch.conf
ssh_host_ecdsa_key
ssh_host_ecdsa_key.pub
ssh_host_ed25519_key
ssh_host_ed25519_key.pub
ssh_host_rsa_key
ssh_host_rsa_key.pub
sshd_config

./usr:
sbin/

./usr/sbin:
sshd.exe*

./var:
log/

This takes 6.6MB while OpenSSH for windows takes 6.5MB.
Almost the same size!
