In 2012 Doug Gregor (Apple) did a presentation focusing on Modules; or more specifically on the "On the Fundamental Brokenness of Headers", and how implementing support for modules in LLVM and Clang would overcome a lot of those issues: "Writing a Module Futuristic Version"; major stumbling points were seen as:
Benefits of moving to modules were reasoned to be:

Many had thought this would't be possible; so was surprised to see the following tweets between the compiler teams at:
... from talks at CppCon:
In short; it's not only working, but Google has enabled in ~10% of its current codebase. So great news -- FYI I'll put up any videos links and slides when they become available.
Here's a related twitter poll on whether macros should be supported for modules, naturally the answer is yes; or as someone put it: "if you argue, you loose". https://twitter.com/meetingcpp/status/779359906667171840

Next pie in the sky:
- Transitioning existing header-based libraries
- Interoperability with compilers that don’t implement modules
- Requires tools that understand modules
Benefits of moving to modules were reasoned to be:
- Compile/build time improvements
- Modules are a huge potential win for C(++)
- Fix various preprocessor problems
- Far better tool experience
- Design enables smooth transition path
