At least, I hope these could be applied to other VMs like the JVM. I don't see any reason why it can't be done, but I'm not an expert at all.

From my understanding, the main issue is mostly that it is very complex / risky to do these optimizations, and the reward is deemed low for the JVM.

The main JVM target I can think about where it could probably be profitable is the Android subsystem, but why would you care to reduce OS / Apps size when the fact that phones get bloated is very good for your business since you also sell phones, so it's quite useful to push the user to renew its phone on a regular basis.
