I thought those were uncommitted because they only made sense as helpers for operator trains, just like how [ and ] are mostly useful for helpers in trains and composes. Meanwhile, if you think they are useful, you could define something like lev =: 2 :'u' dex =: 2 :'v' pass =: 1 :'u' as a substitute to the old [. ]. ]: primitives.
