Wasn't the idea of the release candidate to only fix bugs, not add new
features?
Admittedly, yes. But there's a case for considering this a bug-fix.
I accept Artur's point that having once accepted bundles and strings
arrays as targets for "foreach", it's inconsistent to ignore other
arrays -- that is, treat their identifiers as just dumb strings.
