I'm not so worried about RDA rules on using terms instead of codes. If a cataloger chooses a text term from a picklist, she may think she's recorded the term, but behind the scenes, a uri is recorded. Both sides are happy.

Exactly. I cannot understand why RDA does not, wherever possible, advocate the use of codes instead of English text. And all MARC specimens of RDA data abound with verbiage although codes do exist, as for example in the 33X's. One important aspect  is international exchange and multilingual catalog interfaces, the other is most certainly consistency. As you point out, software should of course be able to catalogers with comfortably inputting codes with not having to know the numbers or acronyms literally, and OPAC software can display whatever text is found suitable for the situation at hand. Imstead, English language verbosity and loquatiousness abound in the data, with excessively long labels in XML designs to make your head spin and at the same time increasing the probability of errors, i.e.
The front end for catalogers will likely be the most important aspect of RDA cataloging if it is ever to become a success story.
It will have to be much more efficient than MARC.
With BIBFRAME, I see little hope of this happening, more to the contrary.
(Furthermore, it doesn't help that the RDA scripture is under lock and key of a global monopoly.)
