The Mint team had to trim a lot of stuff that wasn't absolutely necessary in order to get the distro to fit on a cd. They had a choice, leave out some non-essential documentation that could be easily downloaded, or leave out some programs that they knew users would want/need.
What you see is the results of their compromise. It is an exercise that all distro developers must undertake. Since it is a compromise, it isn't possible to please everybody. You do the best you can and take your licks.
Personally, I think they did a pretty good job.
