Risks of free nipple graft compared to no free nipple graft?

The doctor I spoke to will do the anchor incision, either with or without a free nipple graft. To get to the size I want (which is practically flat), I know I would need to have a free nipple graft. I am not at all interested in ever breastfeeding, so not being able to do that because of the FNG isn’t an issue (I’m also not too upset about possibly losing sensation with it, but also, my doctor said after a FNG the nerves or something will reattach and I will likely get some kind of feeling back). But I’m wondering if any other risks associated with getting a reduction will increase by choosing to have a free nipple graft (necrosis, healing, etc). Basically, I’m wondering if there’s any good reason (aside from losing the ability to breastfeed) why I shouldn’t get a free nipple graft, because it seems like the same thing except with the added bonus of being able to go as small as I want!
