Expending to fully support MSVC x86 and x64 is in my plan.  Right now we only have precommit CIs for shared headers.  There are couple failures to build the libc in overlay mode with MSVC x86 and x64 that I couldn't find time to fix yet.  Probably we will be able to do that, together with precommit CIs, by the end of the year.
