I think that, happily, we can easily put this to rest.

There are already a dozen motivations defined in the model [1], and your
use case did not fit into those 12, as there isn't a motivation that's
explicitly the text to replace target text with.  So in order to fulfill
your use case, you would be outside of the standard too.  The 12 were
already trimmed down from longer lists of motivations by looking across
many use cases and previous research in the OAC and OA-CG days.

In the IIIF use case, we had to define a new motivation (painting), and
that's likely insufficient and we'll need at least 3 further motivations as
narrower concepts of it to clarify expected client behavior (transcribing,
translating, editing [in the sense of creating a textual edition of a
work]) [2].

So, I hope that you can see that 99% of roles really won't fit into half a
dozen, and hence property-as-role really doesn't work for interoperability
without the significant overhead of RDF inferencing to determine how they
relate to hasBody or hasTarget.

Thanks,

Rob
