I'm wondering how you propose to build such JAR files.  Do you think
library developers will maintain two separate branches, compile one with
JDK 8, the other one with JDK 9, and then use some (not yet existing?)
tool to merge the output into a single JAR?  Is such automated merging
even possible if the bytecode was compiled with different javac versions?

What about presenting Javadoc in a useful fashion?
