I think this is reasonable. When aggregating several projects into an aggregate project, it is natural that they are build for the same target and same RTS. No?

Yes. We use an aggregate project to set an environment variable (LDSCRIPT) that is used by the linker to locate the linker script. The value is derived from a scenario variable and it would thus not be easy to set it in the shell before invoking GPS or command-line tools. The aggregate project is thus a simple wrapper around the "real" project.
