More tag truncates feeds without warning

Following the upgrade to WordPress 2.1, my full text feeds are truncated in the feed when I add a more tag (This is okay as Options page mentions this). My only question is if the normal blog page shows at least an indication like ‘Read more’, then why isn’t there such a thing in feeds, if indeed you have tied more to post curtailment.

Lack of indication makes a person, reading the feed, not realize that perhaps there’s more content.
