Benefits of JPMS / Project Jigsaw for Small Applications / Libraries

Question

I understand the benefits of the Java Platform Module System (JPMS) for large applications, but is there any reason to make a small library or application in a (single) module? If so, is Modular Jar Files the best way to achieve this, or your preferred normal approach?

Going forward, will there be performance implications for modular vpath classpath programs?
