To be honest, I'm a bit annoyed that I installed maybe 2-3 extensions, and in the last year or so whenever I open one of their IDEs I need to update anywhere from 10 to 25 extensions. What are these things? Where did they come from and why do I have them, I used to see only the extensions that I actually installed, and now there's all kind of stuff that I thought was basic functionality.

A lot of core functionality is implemented as bundled plugins (they ship with the IDE, but can receive updates separately). They can also be independently disabled (and older versions used to come with only some enabled and ask you which others you want enabled at first launch).
