It's definitely a nice player, but for the sake of simplicity and user-friendliness for new users, I don't think it should be installed by default. However, might be useful in the repos :)
That sounds good, but why not a package in the offical Mint repo`s?
You can add the WebUpd8 PPA and install UMPlayer using the following commands:
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install umplayer
