I think such feature would be useful. I think that following
should be done
1) when ps is run as ps-sysv, it should use the SysV-style
   arguments
2) a flag should be added to force either behaviour
3) if ps not run as ps-sysv nor the flag is given, ps should
   process it's arguments and if it finds a svrish one (such
   as -f), switch to SysV-style and restart the argument parsing
   process - this should be pretty streightforward and easy
   implement, and should DTRT in most cases
