25+ years ago, when Series 80 Colts were the only 1911s with any sort of firing pin block, a lot of people questioned the need, the engineering, etc. Today, when almost every gun on the market has a firing pin block, and Series 80 is about the oldest and most proven design, the overall outlook is different. If the gun is working properly now, it's very unlikely that you'll have a problem with it in the future.
Taking it out is easy, but I would recommend against merely removing the plunger and spring from the slide. I bought a used S80 that had been "converted" that way, and the tip of the frame-mounted lever was wearing a groove in the slide; I could imagine the tip of the lever catching on the edge of the plunger hole, causing a malfunction.
