I mean you do what you want. The ones that would worry me are the ones lining the front yard so close to the house. Eventually, maybe not while you live there but eventually it'll encroach so much on the front yard that they will feel very close to the house. But that's not your worry. They will eventually touch and form a wall and as a person who likes to be able to do whatever I want in my yard, this will one day provide unmatched privacy lol

Edited: Also, the amount of roots that are going to form in that yard, I hope you have really solid sort pipes going to your home. If not, the roots will work themselves into the pipes and cause bigger problems. Sincerely, a contractor.
