>From my observations, Juniper for certain reason does not care about
existing customers on this by forcing everyone moves to flow-mode. And
only provide workaround for customers to run packet-mode by breaking
several functions.

My company has lots of J-series routers with 9.3s13 packet-mode
(legacy) JUNOS. Everything is fine until we need some newer functions
in few specific nodes. After upgrade to newer version, say 10.2r4.8,
we manually turned it into packet-mode. However, we lost some of nice
features such as j-flow and IPSEC. That soon became operation
headache.

The reason we stay in r4.8 for now is because of RAM limitation that
r4.8 is the last release could be installed on 512MB RAM model.
