This looks related to bug 447570 and bug 442830 , but they're not exact matches.

Case A:

> EAPI=4
> IUSE=""
> REQUIRED_USE="test? ( ... )"

Case B:

> EAPI=5
> IUSE=""
> REQUIRED_USE="test? ( ... )"

Case B triggers a repoman warning, but case A does not.
In case A, "test" is injected by config.py 

> iuse_implicit.add("test")

Case A has the unfortunate side effect of the REQUIRED_USE segment being ignored by Paludis due to the absence of "test" in IUSE.

Case C:

> EAPI=4
> IUSE="test"
> REQUIRED_USE="test? ( ... )"


Case C has Paludis correctly respect the REQUIRED_USE statement.

Unfortunately it is probably not immediately practical to fix portage to break the same way Paludis does ;). But having repoman warn here would be a good start.

We can probably call this obsolete given there’s no more EAPI 4 ebuilds in tree. Obviously Portage will retain support but I don’t think there’s any appetite to enhance repoman for banned EAPIs.

Closing.
