Will PDF xchange viewer be added to the list of monitored software for the updater?

It was also the the most popular Adobe alternative reader according to a Lifehacker.com poll by a large margin years ago, so it isn't some obscure piece of software thus has a large enough user base to warrant monitoring it.
