Yes, adding extra space and resources for a feature that cannot be removed and is preinstalled is basically the definition of bloatware.
And do you know what "some" means? It's a word meaning "an unspecified number or amount of people or things." I don't have a stat that has an objective measure. But I do see three people in this thread that don't want it, so it's applicable. The very reason I included the word "some" was to avoid arguments like this one, where a bigger metric would be applicable. So, yes, some people don't want the App Library taking up space on their phone using resources for something they don't want.
Now, since you're into being needlessly pedantic (and wrong), I want you to forward me your stats and study for "everyone I know that has an iPhone" who told you they are "really liking the App Library." Somehow, I think you didn't poll everyone you know. That's exactly the type of hyperbole I avoided by saying "some/most."
