I'd be grateful for pointers to the following:

  • Good discussions of the specific security threats posed by the currently disabled Script operands and the prospects for enabling them in the future.
  • Good discussions of extensions to the scripting language, their utility, the security threats they pose, and the prospects for their future implementation.
  • Good discussions of how and why to implement the currently disabled operands.
  • Good discussions of the speed of adoption of updated clients and mining software.

Bump.  I'd really appreciate some help with this, because the term "script" is hard to google usefully for. :-)

They're not disabled because there are known attacks against scripts using them (although there may be for some), they are disabled because they are not needed (yet).

EDIT: I stand corrected.

No, that's exactly why they were disabled:
