Remove Keyframes with scripts. Not one keyframe at a time, because that's too painful!

Let's start off by acknowledging one of the efficient features in After Effects that allows us to remove keyframes from any property simply by clicking the time-vary stopwatch. It's like an undo button for commitment. 

 

Recently, I've been baking in some expressions for a comp. To speed up my workflow, I've run some expressions that tailor each comp according to a CSV file, essentially creating a dynamic racing scoreboard. However, this process has a minor downside - it's like a really enthusiastic party planner, it puts a keyframe on every single frame. So, I manually hit the time-vary stopwatch to blast away the keyframes - a quick fix but not ideal considering the multitude of layers and properties in play.

My initial thought was to script a solution to obliterate these unwanted keyframes. While it works as intended, it's a bit like watching a snail complete a marathon. It iterates through every single keyframe on my selected properties, which is just painfully slow. I've found that I can manually click the stopwatches faster. Much faster. But, alas, carpal tunnel syndrome is not on my bucket list.

 

So here's the Magic question: Does anyone out there in the After Effects world know of a way to script the equivalent of clicking the time-vary stopwatch to deactivate keyframes? If such a magic trick exists, I'm all ears, and it would completely make my feature request redundant.

 

However, if I'm correct (which usually happens only on every alternate Tuesday), I've got a request. Can we possibly gain access to the time-vary stopwatch feature via expressions? It can't be too hard, right? After all, you've already designed this wonderful function - all we're asking for is a backdoor. I'm begging can we get access to this feature?
