Too many variables, but they will be there; and over time may need to be repaired. Know the risk and use best judgement. My OPINION is some would be fine, but minimize where you can.

As a structural build I would be very cautious.
However if you are thinking of building an RMH or a pizza oven then your roots would be no different than added straw.
