It's weird that the three anniversaries are so close to each other. I wonder if future generations will see late January as an "unlucky" time to board a spacecraft.

According to Stack Exchange, such systems have been proposed for nuclear reactors, because it would be a Very Bad Thing to leave it on a rocket on the verge of exploding.

Otherwise, the money and engineering effort it takes to build a launch escape system is simply better spent on making the original launch successful. Or just building a replacement satellite.
