Strongly in favor. Such a modularization will be a benefit for CMake. It
will require to cleanup CMake's internal inter-dependencies and it will
help to keep them clean afterwards.
It will make CMake's codebase easier to approach by new contributors. It
will allow experiments like replacing individual parts (eg. new frontend).
Let's learn from LLVM/Clang.

Don't merge the commands with the command interpreter/vm.

5) Scripting commands
6) Project commands
7) CTest commands
8) Package generators
9) Server
...

True cmake power is in its generators. It's always possible to rip off

Personally, I regard the generators as obsolete and see the future in the
server.
