It's all but dissapeared these days, which is a good thing considering how incredibly addictive, cheap and untested that shit is.

Consider the development of so-called downtoners – grammatical elements that minimize the force of the word they accompany. Nineteenth-century English saw the emergence of a new downtoner, all but, meaning 'almost'. All but started out being used only with adjectives, as in her escape was all but miraculous. But later it also began to turn up with verbs, as in until his clothes all but dropped from him. In grammatical terms, that is a fairly big leap, but when looked at closely the leap is found to go in smaller steps. Before all but spread to verbs, it appeared with past participles, which very much resemble both adjectives and verbs, as in her breath was all but gone. So, changes can sneak into a language and spread from context to context by exploiting the similarities between contexts.
