Angry Forgot to air seal before installing Roxul batt insulation

I just installed roxul comfort batts in the single exterior wall in my kitchen not knowing that I should have air sealed the wall cavity with Great Stuff.

Should I go back and air seal? I read somewhere that Roxul is dense and relatively airy tight compared to fiberglass.

I roughed up the edges of the batts a little when I was installing, so I'm worried that pulling it out and reinstalling may decrease the R value.

Unless you literally have holes through the wall you will be fine.
