Dear Anna,
I've never heard of that before, but I don't think you have to worry. I've found that unless we paint in some mysteriously weird way, oil paints are much tougher than we are led to believe from books.
My first oil painting was done on unprimed paper 56 years ago. It is STILL just fine. No rot or decay from oil on paper in spite of what the book says!
Try your clear acrylic gesso. If you have problems, they will probably show up right away. When the paint dries, scratch it with your fingernail. If it comes off in a sheet, you are in trouble! Otherwise, be happy.
