[petsc-dev] overly complicated TS?

    Jed and other TS folks,

     Since you introduced providing the ODE/DAE in the form F(t,u,u_t)  
= 0 and it seems universal is there any reason to keep all the old  
crap around at all?

     I hate complications. Why not just require the user to provide  
this way and not support right function, right matrix, left matrix  
blah blah blah. Seems it would simplify implementations and mess that  
has to be maintained greatly?
