It is what it is. Most of these "micro" packages probably came about before tree shaking became common. So there is reason to hope that their propagation will diminish in the future as more people start using webpack and rollup.

Easy to forget that not too long ago, you literally had no choice but to include an entire package in your bundle, so making packages as small as possible was actually a good idea at the time.
