I'm not entirely sure what you mean by linking support so the following
may not be relevant.
Build time is not the only reason for not wanting to build entire
projects together.
When creating an Emscripten config from an existing MSVS solution that
is configured as multiple projects (e.g. a library and several
applications) you want to retain the structure. I have such a solution
currently using the old compiler. There the library build generates
bitcode. As I understand it, the application compiles generate JS for
the library and application.
One may want to deliver a library for people to use without providing
its source code. The bitcode file would work for this too.
