USABLE anchor and handle advancements

Question

It seems that with all the CS5 updates, especially PS CS5, the new features only reflect the most popular plugins available.
SO.... why has illustrator not implemented any of the extremely useful plugin ideas developed to improve anchor and handle adjustment.
My primary example is that of BetterHandles by nineblock: http://www.nineblock.com/products.html#betterhandles_prod
It adds all the features I really need when trying to fine tune my bezier curves:
Select multiple handles, and collectively move,  extend, rotate, or retract them
Extend or retract handles without changing  their angles
Copy and paste handles
Edit points numerically: anchor, in handle, out handle
Convert multiple points from corner to  smooth or vice versa
Automatically extend new handles on multiple  points
Intuitively reshape path segments,  optionally constraining handle directions
Use slow-drag to divide the cursor movement  for extremely precise moves
Equalize a point's handles
See all the handles on a path while editing  it
Split a path at one or more points
Delete one or more points and close the path  around them
Remove all redundant points on multiple  paths
See when the cursor is over a handle, point,  or path — without having to use Smart Guides
THESE SHOULD HAVE BEEN IMPLEMENTED IN THE CS4 UPDATE LET ALONE CS5. If it is an intellectual property issue, adobe should enter a contract with the rightholder and integrate it, I'm sure it will be more profitable for the owners than the random stumble like me.

Wow that plugin sounds nice.
Adobe should spend less time adding new features and more time "fixing" the ones they already have.
