While I agree your opinion from a user perspective I don't think this can 
happen with the proposed algorithm. bar-ng can only pulled in while there is 
a package requiring it. What can happen is:

yum install foo bar

results in installing foo and bar-ng as bar-ng is needed for foo and bar 
cannot be installed. But sorry, that's the best you can get in this situation.
