Finally the concept of meta-package should be extended in my opinion. If it does not make sense for meta-packages to declare other dependencies than the packages they "contain", then the standard should forbid this (and validate that), meaning the meta-package tag should not be in the exports section and should have an alternative syntax where things are not allowed. E.g. may a meta-package have a CMakeLists, have sources, generate executables, etc.? If not, the REP needs to say so, in my opinion.
