Comment:
My idea is that it won't at all help moving files to OOo or Office but
will help with the use case of someone using Abiword as their word
processor on a daily basis.

This way we get the advantage of abw (perfect reproduction for Abiword
users but no help for any other word processor) mixed with the
advantages of odt (portability to other word processors, even if it's
not perfect) without the user having to be aware of the idea of "file
formats" or having to manually switch between them.
