It is already there, the exception's class-description says
"... relative get/put operation ...", and relative operations are
specified to increment the buffer's position. What we are/were
discussing is/was possibly removing this relative-only operations
restriction.

All current usage that I can find has no regard to whether, or not,
there is adjustment to the position. The only factors regarding the
raising of the exception are the current position, the limit, and the
given, or implicit, length argument.
