Actually libraries that target Android need to use Java 7, unless they want to constrain their users to API 26+.

Is newer Android fully JVM-8 compatible? It'd be great to be able to start using Scala 2.12 even if it means I have to restrict to new devices only.

Not really, a lot of desugering still takes place into DEX bytecodes.

Stuff like lambdas take extra memory, because they convert into anonymous innerclasses instead of invokedynamic.

As far as I'm concerned that's an implementation detail. If I can take arbitrary JVM8 code and run it and expect a correct result then that's a huge improvement for my purposes.
