   I am curious why continue to use dropbear anyway?

   The openssh-sftp-server will likely work better with openssh than 
with dropbear.

  Openssh uses only about 3MB more per session than dropbear, which is 
small unless you need a lot of simultaneous sessions.
I think dropbear is a relic from when systems had less RAM.  Just 
curious.  Maybe I'm missing something.
