I could certainly go along with that ... reducing the proportion of control files returning untyped strings.
My sense of kernel-user API's is that usually the less said the better. Identify the essential information that one side requires from the other via a runtime API, and pass only that. API's represent a lifetime commitment, so the less promised the better.
Perhaps my primary concern with these *.api files was that I did not understand who or what the critical use or user was; who found this essential, not just nice to have.
