By convention adopted from the various original OF/ePAPR/etc specs, the only properties I would expect to see with this prefix are the "*-cells" cell sizes. A quick search indicates this is the case throughout all the current bindings.I always assumed that the # prefix is used to indicate that we are counting things instead of listing them.
Your assumption is historically correct. It seems that usage has drifted somewhat.
