If it's an official feature that these modules are always built, the patch is insufficient: it then also needs to adjust the build environment for Windows, and the packaging. It potentially also affects packaging for OSX and Linux. I still think that users with special needs such as (1) and (2) in the original message are better served by editig Modules/Setup, as that also allows e.g. to make the modules truly builtin.
