While I can appreciate nicely done ink on a girl, as a shooter, I'm not a big fan of tats on models (I like to start with a bare canvas)...
These days, I tend to shoot girls with their tats uncovered, since as you noted it is a pain in the ass to do anything about tats for video, and there is a market for girls with tats.
I sometimes take out tats in still photos for promo galleries, and leave them in the video - it's funny when a model complains that I removed their tats in the stills, while also admitting that the photos actually look better without the tats.
BTW, I've never had a Member complain that the photos and videos did not match due to tat removals in the stills.
I wonder how many hours it takes to cover up Angelina Jolie:
