I agree that 'rudimentary' isn't necessarily wrong. But if one happens
to have a definite belief as to whether the rudiment is something new
coming in or something old going out, the language should reflect that.
'Rudimentary' and 'primitive' and 'basic' are all often ambiguous in
this sense, unlike 'vestigial' for old, and 'incipient' for new
structures.
