C++ Modules

Hello All,

I came across a paper by Nathan Sidwell entitled, 'Make Me a Module':

                https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1602r0.pdf

I was wondering if there are plans to add support for C++ modules to gnu make. If so, has
there been any estimates on beta availability? Is this being blocked due to some modules
functionality not yet implemented in gcc? I noticed this link shows some modules support
in gcc as incomplete:

                https://gcc.gnu.org/projects/cxx-status.html#cxx20

Thanks,
Kenton
