Not regenerating configure doesn't pose any significant risk that we're shipping a configure script that we can't regenerate (or, at least, regenerate an equivalent or better one).
Autotools stuff tends to bitrot, just like everything else. There's a reason we have 4(+1) versions of autoconf and two versions of automake in jessie.
I've not heard of people (for example) using private autoconf macros not included in their build tree.
