Should you also remove fips_set_state(true) and make fips_get_state()
return the contents of /proc/sys/crypto/fips_enabled, so that VNC
password authentication is disabled?
I did think about doing that, but decided that since my intention is
to delete all trace of fips_get_state / fips_set_state at the end of
the deprecation period, that it'd be saner just to leave the semantics
unchanged during the deprecation period.
Deprecation notices shouldn't really be associated with changes in
functionality at time they are introduced.

Daniel
