I think that throwing out ratpoi entirely would be a mistake.
Appropriate documentation could explain its purpose and allow interested
persons to construct the rational (CRE) coefficient version.
Perhaps conditionalizing the code somehow like #+RATPOIS (......)
The point is that under some circumstances the RATPOIS setting would run
important problems 1000X faster...
This is not something that the test suite tests for.
