When you say "always be live," do you mean that the path and
associated stroke would always be editable? Like a true vector 
object?

Basically, we'd be talking about different usages of the path tool 
then. It's the difference between moving a piece of string on paper 
(you can keep moving it, but there's only one line), and using a 
curved ruler to help you draw lines on the paper (you can move the 
ruler as much as you want, and draw as many lines as you want, but 
short of undoing everything you can't modify previously drawn lines).
It's true that many Gimp users seem to use the path tool primarily for
the second purpose, along with its benefits and drawbacks.
