Yup, frequently.

I can't claim to know what "most" users do. I know that multiple
software vendors have independently hacked OpenSSH for use in DoD (do a
search on "site:csrc.nist.gov/groups/STM/cmvp/documents/ openssh" and
you'll see a number of validated modules that specifically mention
OpenSSH). I also know from consulting within DoD for many years that
OpenSSH is often used unmodified, a policy violation that often went
completely unnoticed. As a consultant I hacked OpenSSH multiple times
for DoD clients and vendors to DoD clients, and I'm sure I wasn't the
only one. There are also a handful of commercial knockoffs of OpenSSH
supposedly adapted for DoD compliance, though I've been out of that
arena long enough to no longer recall their names.
