:tlong made a good point elsewhere: Won't the libraries have to either try and initialize, or wait for initialization before they can do anything with Glean? I know that the init function throws an IllegalStateException but is that going to be an issue for a consuming application/library? I know that it can be handled with a try but that seems like a harsh way to indicate that the library is already initialized. Also, what happens if a library tries to initialize with a different configuration?

I would summarize this as: Make sure initialization is as straightforward and fool-proof as possible in light of the new multiple-libraries-using-glean-together world.
