I'd like to add that I concur with the original post. One could say (grabs
the number-filled hat) that 70% of MI uses are plainly bad and 20% are ok
but can be done better in other ways (aggregation, etc). Note that I see
inheriting multiple interfaces as something different from "general" MI.

Can you explain more carefully? I didn't really understand the second rule.
