Experts,
out of the well-known values for ip options:

X at jr4# set ip-options ? 
Possible completions:
  <range>              Range of values
  [                    Open a set of values
  any                  Any IP option
  loose-source-route   Loose source route
  route-record         Route record
  router-alert         Router alert
  security             Security
  stream-id            Stream ID
  strict-source-route  Strict source route
  timestamp            Timestamp

I can only think of:
- RSVP using router-alert
- ICMP using route-record, timestamp

But I can not think of any other use for other types of IP options.
Considering the security hazard that they imply, I am therefore thinking
to drop them.

Do I missing something important? What is your opinion?
Thanks,
Bit.
