In my brief look I haven't found anything definitive about the source or sources used by this extension. If it is purely based on Have I Been Pwned then it would be mostly redundant given 1Password 7 integrates checking already in Watchtower. If it has other sources then it could be complementary. I don't see anything that suggests there should be any interference either way between it and our own extension though which I think is your concern. If that wasn't what you were looking for please let me know.
