The idea is probably that they’re the most popular plugins, and most people are using some combination of them already (as you yourself are). It’s not really “bloat” because they have pretty much no footprint, and you don’t have to use any of them for anything. This is a lot different than having 20 programs I don’t want installed on Windows, these are on/off toggles (most people won’t see, and you as an admin will have in a list of 300 other things you already aren’t using/changing) not something that is constantly coming up/taking up actual space/set to do things by default. Having a note program installed by default that I don’t want means I’ll end up having two. Having a plugin I don’t want means there’s just an option sitting in a panel
It’s also a lot easier to have on/off switches then having to search through a third-party forum (or endless githubs) looking for something you don’t even know exists in the first place. This was actually the first time I was even aware of a handful of these
