I think your points are reasonable and I see no impose arguments
about not use it the guideline for future wrappers.  How should
we document this principles for future references: a documentation
file in source code or just wiki entry in sourceware.org?

Also, for arch-specific syscalls, should we apply to same principles
or may the maintainer be able to discuss more specific points (for
instance, the usage is limited to a set of programs/libraries)?
