Stop using exports like export * from "./somefile"

Discuss and possibly implement the following suggestion:
#5771 (comment)

"... I noticed is that every package has indexed with exports like export * from "./somefile", I think it's a bad practice because:

• if you are exporting everything from every file, every change is gonna be breaking change - maybe consider exporting only stuff that developers or you actually need
• if the developer is searching for the source code of some imported class, it's gonna be a nightmare because it could be in any of these files so you can't just ctrl+click to dig through source code

@mconnelly8 This is not breaking change really. Any reason why you've pushed this to 5.x?

@mpetrunic The team discussed this and determined it was low priority and scheduled for v5. I don't remember if this was questionably a breaking change. Maybe @jdevcs or @Muhammad-Altabba might remember that.
