I've trained abs a couple different cycles and did them HST style. If you want to get some size in your abs, which will make them look better when you have low enough bodyfat for them to show, then by all means do them HST style. So yeah, hypertrophy of the abs is a good thing. If you have little tiny abs then when you cut down low enough for them to be visible, they will not look as aesthetically pleasing.
Personally, I've found that these days, ab exercises are unnecessary. Although I rarely ever train abs directly, I can do situps, crunches, etc with so much weight now due to all the compounds I do that it is almost pointless to hit them directly. But that is talking about ab strength. I don't know if deadlifting, etc is responsible for my abs being as thick as they are - it could be due to the cycles of HST where I did ab exercises.
So... I would suggest doing them for a cycle and seeing what happens.
