Tentative was not a problem a couple years ago when one or two people did that who were known to the hosts and were just passing along informal information about their status.
However, lately "tentative" has become an official status. I've seen games where 50% of the listed individuals are tentative and those saying tentative nobody has even met before. Tentative is no longer meaningful as a result.
