Couldn't agree more.  To do this right, however, requires implementing
"provides" clauses first, and that's unlikely to happen in the next
two weeks.  Modules named "jdk(\.\w+)?" are ultimately intended merely
to be artifacts of our implementation; applications, if they declare
an explicit platform dependence, will refer to abstract modules named
"java(\.\w+)?".  We will actively, and perhaps mechanically, discourage
people from referring to "jdk" modules.

In the meantime, org.openjdk.jigsaw.Platform.isPlatformModuleName(String)
will tell you what is, and is not, a "platform" module.

Yes, but for demo purposes I'm mainly using single-module source and
classes directories, in the traditional layout.
