Is there a collection of presets for the included stock-plugins that come with AE?

In looking through the stock effects that come with AE, I noticed that presets are few and far between, specifically the Animation Preset field is nearly always devoid of options.

I'm unclear as to why AE wouldn't want to include presets, as it would seem there would otherwise be a massive duplication of efforts from users all creating similar presets vs. starting with a few good ones.

So I'm wondering if there's a collection (e.g. a zip file) containing such a collection of presets for the stock effects that can be downloaded and simply added to the relevant folder(s) to take advantage of them?
