Having just posted that, I thought of this: use of a Transition resource 
makes sense only if all the 'prior_to' resources have a 'before' 
relationship with the final state of the transitioned resource, so in the 
event that the transitional state is successfully applied, but one or more 
of the 'prior_to' resources fails, the final state of the transitioned 
resource normally will not be applied.

I think I'd place that in the "nothing ventured, nothing gained" category, 
though.  That such a risk exists should certainly be documented, but it's 
no reason to nix the idea.  If such a risk is intolerable for some 
particular resource then no transitional state should be modeled for it.  A 
full-blown type and provider may be the only viable solution in such a case.
