Weren't modules created by Herb Sutter at Microsoft to improve the VS201x IDe and compiler? If this is the case, it seems a big player in the tooling world is already on board.
Google improved that implementation for C++ and has a private implementation of it in use.
Gabriel dos Reis picked up some ideas from a former work he did together with Bjarne for MSVC++.
The ongoing C++ Modules TS is to merge the ideas from both sides into what will become C++ Modules.
The history of modules you provided is helpful though, thanks.
