Yes, it has been discussed before, and No, nothing came out of it...
I would prefer something like
0 L3P OPTIONS -cc-1500,-72,-400 -cla-1420,-120,-200 -ca62

0 FILE model.dat
0 L3P IFPOV
0 #include "hills.pov"
0 L3P ENDPOV
If placed at beginning of DAT file, the include statement will be placed in the beginning
of the model object description:
#declare model_dot_dat = union {
// FILE model.dat
// L3P IFPOV
#if (1)
#include "hills.pov"
// L3P ENDPOV
#end
object {
...
which is probably not what you want.
I guess a new option is necessary, e.g. -ihills.pov

// v is now angle (in radians) of left arm and right leg
