I haven't seen the stuff, so I can't say for sure,  but I would expect that it would be a bit "too solid" to be able to inject,  and too smelly not to incorporate.

I hear you on the the fact that it will require more solids, and more work to compost.  For some people, the extra work and aggravation would be worth it, to have a composted product;  for others, they will say "No thanks."  I was just tossing an idea out for consideration.
