I don't think this is the case. Instead I think there is a lot of 
potential for a much better story. Modules lend themselves to doing a 
lot more at build time and setting things up for simple/fast checks at 
startup (think post resolution checks).  It's not hard to think about 
fail fast if a module requires the "restricted methods or native code" 
capability that has not been granted. Combing a set of modules at link 
time also has a potentially interesting story when using jlink to create 
an application that has an initial/main module. In that case, you can 
think about checking capabilities (or whatever term is introduced) at 
build/link time.
