By sheer coincidence, earlier this week I was pondering a project, 
wondering how on earth to do automated fitting of a curve through animated 
points using Beziers and their nasty off-piste control points, starting to 
read about splines, and starting to go off the whole thing.

So yes, please, as a dim occasional author with ideas, I would find 
real-time curve fitting very useful. Ideally, <path/> would have a new 
element, say 'F/f', which would be followed by any number of co-ordinate 
pairs.

Oh, and yes, a more 'normal' means of specifying circular arcs would be 
nice too. At present the only way I have found to SMIL animate the drawing 
of a circle from 0 to 2pi is by hacking it with animated stroke-dasharray 
parameters on the calculated circumference of a whole circle. Friendly?
