Can you honestly not read?
Note: In the following explanation, parts in square brackets ( "[" and "]" ) denote things that you should be able to infer from the text, also known as the "subtext".
The original question was a two-parter. Part 1: "Do the mediavps include ma-sdrvfix.vp?"
To which the answer is, YES [, they include the fixed shaders].
Part 2: "Should I delete it? ["it" being understood as a reference to ma-sdrvfix.vp, refer to part 1 of the question for details]"
To which the answer is also YES [, you should delete it].
Now, WHY you should delete shaders that are obsolete, may conflict with newer ones, AND ARE ****ING OBSOLETE, I leave to your imagination.
