I'm looking for a word or a phrase (preferably a noun phrase) that describes
- something current,
- which should not be still present, because it is kind of outdated,
- but is still around us because of historical reasons.
Naturally, what should or should not be present is subjective, and by using this word one actually expresses an opinion on the matter. Please note, that it doesn't have to have negative connotation, e.g. a character might observe that the world should have moved already, but he or she is glad that it didn't. I'm most interested in neutral or negative flavors, but I would appreciate other suggestions as well.
In a sense it is an antonym (or dual) for 'anachronism', because instead of author-inserted out-of-time thing we have author-wishes-to-be-removed current thing.
What word or a phrase would best describe such a thing?
