Why do they obfuscate if they're just going to provide the mappings?

Proguard can also apply optimizations while it obfuscates. I think a good JVM will eventually do most of them itself, but it can help code size and warm-up. I'm guessing as JVMs get better and everyone is less sensitive to file sizes, this matters less and less.

And there's no way to do only the optimisation part? Surely you could optimise without messing up class and method names..?

Well, maybe that's why they're not obfuscating anymore.
