Obviously compiling a single JDK 9 module-info file seems
pretty cheap, but if you think about the fact that you will want to have a
JDK 8 installed to compile your classes, plus a JDK 9 Jigsaw installed to
compile the descriptor, and then add that you have to fork the compilers,
the cost of this operation is visible both in terms of infrastructure and
build time.
One thing to keep in mind is JEP 247 and the new javac -release option.
Yes, a big change from today's world where the older JDK is used to
build but it opens up the possibility for these more complicated builds
to have only one JDK on the build system. There's a connection to the
multi-release JAR proposal in JEP 238 too.
