Here is again an item that was retracted from last month's agenda,
in modified form. This time, it only affects the syntax of dependency
groups but not their truth value:

I request the Council to approve a PMS change, namely to ban empty
dependency groups like "|| ( )" or "foo? ( )".

Currently, any parenthesised groups in package dependency
specifications [1] are permitted to contain zero items. As was
recently discovered, Portage was changed in 2011 to treat empty
dependency groups as an error. Apparently nobody has missed the
feature for six years, and no ebuild (or eclass) in the Gentoo
repository is using it.

I see removing empty groups retroactively for all EAPIs (therefore
tightening the rules for ebuilds) as the best path of action, because
ebuilds cannot rely on proper package manager support for the feature.

Proposed patch for PMS is in [2].
