I think people are making an assumption that a track bike will be twitchy without understanding trail and rake. A shorter rake fork can offset the steeper head angle making the trail equal to a longer rake shallower head angle frame. And we are only talking about 0.5 - 1 degree on head angle and up to 1 cm on fork.

The thing that makes track bikes worse/dfifferent on the road for me is the higher bottom bracket and steeper seat angle which puts the body more over the front of the bike hence putting more weight on the bars and creating different handling. This may be what some people don't like?
Which is one of the reasons why it is a good idea to look at the top tube length compared to the seat tube length.
